Yikes, I get busy for a day and find that the thread has doubled in size

In the interest of fairness allow me to quote a few things from the book.
"Attributes are the inherent characteristics of your shadowrunner, the basic abilities they bring to the table. Shadowrunners have a numerical rating for each attribute, which is used to help determine the amount of dice rolled for tests in the game. Attributes fall into three different groups: Physical, Mental, and Special. Every character has a rating in each of the Physical and Mental attributes, though they may not have ratings in the Special attributes. For humans, all attributes are between 1 and 6, though certain modifications and qualities can change this. Metatypes have different ranges in these attributes, as seen on the table on p. 65."
"LOGIC (LOG) The Logic attribute measures the cold, calculating power of your rational mind. Whether you are attempting to repair complicated machinery or patch up an injured teammate, Logic helps you get things right. Logic is also the attribute hermetic mages use to resist Drain from the spells they rain down on their hapless foes. Deckers also find Logic extremely useful, as it helps them develop the attacks and counterattacks that are part of their online battles."
"CHARISMA (CHA) Charisma is your force of personality, the persuasiveness and charm you can call on to get people to do what you want without having to go to the trouble of pulling a gun on them. It’s not entirely about your appearance, but it’s also not entirely not about your appearance. What it’s mostly about is how you use what you have—your voice, your face, your words, and all the tools at your disposal—to charm and/or intimidate the people you encounter. Additionally, Charisma is an important attribute for shamanic mages, as it helps them resist the damaging Drain from spells they cast."
"Skill ranks are independent of attributes, but they don’t work alone. The most common dice pools that you roll when you take actions comprise one skill and one attribute. You can study until you know every aspect of Spellcasting, but if you don’t have the raw Magic ability (as measured by your attribute) to apply it, you won’t be as powerful as you could be. While a skill isn’t always paired with a single attribute, each skill has a linked attribute to which the skill is most closely related. This doesn’t mean you’ll always roll a skill with its linked attribute, but you’ll see the two together a lot. A list of linked attributes and their skills appears on p. 151."
"SKILL RATINGS
The higher your skill rating, the better you are with that skill. Someone without the Pistols skill has watched enough trideo to understand that you point the weapon away from yourself and pull the trigger, but that doesn’t make them as good as a character with even an introductory skill level who has a decent firing stance and knows enough to check the safety before firing. The skill Rating is a numerical value ranging from 1, representing the most rudimentary skill, to 12 (or 13 with the Aptitude quality) representing the height of sentient achievement. When you see them written, the skill rating comes immediately after the name of the skill. Rating 5 Hacking is written as “Hacking 5” on the character sheet and in other game materials. A skill’s Rating adds to the number of dice you use to perform the action with the skill. The rules will call for the skill and an attribute to go along with it—just add the Ratings together and pick up that many dice. For example, hitting a Halloweener over the head with a metal pipe calls for Clubs + Agility—if your Agility is 3 and your Clubs skill is 4, you get 7 dice for the attack."
"This is a list of what the skill Ratings mean, so that you can get beyond the numbers and see where your character falls in the general scheme of metahumanity.
NO RATING: UNAWARE This is something other than having no ranks in a skill—this is a special level of ignorance. You haven’t the first clue about this skill. This level can only be achieved through a quality (like the Incompetent negative quality, p. 81), or maybe a character history explaining the deficiency. You can’t default the skill, and it never really occurs to you to even use it to solve your problems.
RATING 0: UNTRAINED The default level of knowledge obtained through interaction with society and the Matrix. Though untrained, you have a general awareness of the skill, and occasionally may even be able to fake it.
RATING 1: BEGINNER You have a little training about how it works, but not always why it works.
RATING 2: NOVICE You’re a hobbyist, but not an enthusiast.
RATING 3: COMPETENT You’re skilled at basic operations but struggle with complex operations and “tricks.”
RATING 4: PROFICIENT You’re comfortable with what you do and perform well under normal pressures. Professional level for most jobs.
RATING 5: SKILLED You know how to handle yourself in unfamiliar situations, and can get creative when solving problems.
RATING 6: PROFESSIONAL You could easily sell your skills on the open market. This is the maximum skill level for starting player characters.
RATING 7: VETERAN You’ve seen a lot of what the skill can do, and what it can’t. Other people ask you how to do it.
RATING 8: EXPERT You are a highly sought-after talent. Corporations seek you out (or extract you from other corporations).
RATING 9: EXCEPTIONAL Your name is synonymous with the skill. If you have multiple skills at this level, you’re lauded as exceptionally gifted.
RATING 10: ELITE You are famous, even among the very best in your field.
RATING 11: LEGENDARY You are a paragon to those trying to excel at your skill. Techniques are named after you.
RATING 12–13: APEX You have reached the pinnacle of mortal achievement. This expertise represents the top 0.00001% of all practitioners in known history. The very highest rating, 13, can only be reached with the Aptitude quality (p. 72)"
Here are my thoughts.
What does your skill rating represent? "The higher your skill rating, the better you are with that skill. Someone without the Pistols skill has watched enough trideo to understand that you point the weapon away from yourself and pull the trigger, but that doesn’t make them as good as a character with even an introductory skill level who has a decent firing stance and knows enough to check the safety before firing. The skill Rating is a numerical value ranging from 1, representing the most rudimentary skill, to 12 (or 13 with the Aptitude quality) representing the height of sentient achievement."
What does your attribtue rating represent? "Attributes are the inherent characteristics of your shadowrunner, the basic abilities they bring to the table"
What does your dice pool represent? It represents the combination of your inheritant characteristics and your efficiency with a particular skill.
Base on all of that, which is directly from the core book, I think you should be able to see how I've formed my opinions on these matters.
Now let's talk about attributes.
As some of you pointed out, having a low attribute rating does not mean that you are at the bottom level of capability in the respective attribute. A person with a charisma for 1 does not have any specific disadvantage, it represents his overall ability to interact with and manipulate others. That person is unlikely to be able to get people to do what he wants unless he has high skills ratings, gear, magic, etc. A person with 1 logic is not mentally challenged or even extremely stupid, he is someone that struggles with certain technical tasks within the game.
Which brings me back to my point about dump stats. All attributes can be detrimental during the game if they have a rating of 1. It is the GM's job to both recognize this and decide whether or not to utilize it to enhance the quality of the game. The Street Sam with 1 Charisma and no social skills should have a hard time in a complex social situation, such as attending a fancy corporate party and attempting to maintain his disguise. You also need to consider attribute tests and tests such as composure and memory. It is my opinion that it is perfectly acceptable to begin the game with any rating in any attribute. Stating that having high or low ratings is power gaming would be false imho. Low ratings can be very immersive and entertaining and removing the player's ability to select them is essentially taking an element of fun out of the game. Some of the smartest people I've met in life were also the last ones I'd take with me on a run, and some of the dumbest could be the best. I don't think polarized stats need to be discriminated against.
Regarding the distiction between dice pools, attributes, and skills, I do think that your skill rating matters a tremendous deal, but only for immersion. If you don't place a huge importance on it then it wouldn't be an issue for you. But I can not imagine a guy that tried in college, was very intelligent, and left with only rating 1 Biotechnology. He may have bioware to boost his brainpower and he might even have SOTA tools at his disposal, but I feel it would be somewhat immersion breaking to say that he graduated from college with a degree in biotechnology, even if he has a dice pool of 15. It is nuances like this that make me place a large importance on skill ratings and I tend to think of both the attributes and the skills to reach the level of immersion I prefer.
