Not that Improved Attribute is a great pick.

It's a very good pick once you get your attributes maxed or start raking in extra power-points with Initiation.  Of course, it's only good for adepts who are focusing on the more physical things.

Compared to Attribute Boost, not really. Attribute Boost [Agility] 4 is the same price as Improved Agility 1. Magic 6 + Agility Boost 4 is a 10-dice pool to raise Agility 1-for-1 per hit and it's likely you'll get more than 1 hit on that pool, which would make it pretty hard to do worse with it than the flat +1. Hell, take boost 2 for 8 dice at half the PP price of the flat +1 and you'll still be likely to get at least 2 hits.

And then there's Strength and Body.  Attribute Boost doesn't apply to melee weapon damage or a few other things, and having a higher Body is just nice (extra soak, toxin/drug resistance, more physical health boxes, better endurance, etc.).  Sure, Agility and Reaction don't get as much of a benefit from Improved Attribute, but it's not to say Improved Attribute isn't a very useful power.  It's sort of nice to not have to activate your boost, which a flat Improvement helps.  Also, technically Attribute Boost doesn't make your character faster, as the adept power applies to rolls, not flat stats like your Agility for movement rates.

And then there is the Way of the Athlete, which makes Improved Physical Attribute (Agility) cost only 0.5PP, causing no drain, always active and increasing your movement rate as well as helping with things like jumping distances, some reloading mechanisms.

Not everyone plays a gunbunny that can attack with simple actions.
Improved Physical Attribute (Reaction) could be the 4th point you want for your augmented maximum, when you're already at IR3. They are really nice for rounding a build out.

With Iajutsu a Melee Attack becomes a simple Action and for an Adept with Quickdraw even a free Action

Get rid of the Idea that a melee attack is  always a complex Action (most often yes, but not always)

Mentioning Iaijutsu is of no use, since it is another simple action to be used. So you can't combine Attribute Boost, Iaijutsu and a Melee Attack in the same Action Phase.
Additionally I doubt the combination of Rapid Draw and Iaijutsu is even possible, since both modify the Quick Draw Simple Action independently of each other. And since you already used one method to draw the weapon, you can't use the other to draw it (at least if it's the same) again.

PS:
Additionally I find it quite astonishing that Rapid Draw would allow you to attack as a Free Action. Maybe they forgot that they changed Quick Draw to include an attack during the edition change?

[Novocrane]

I don't think so, Lucean. You still only get one attack per IP.

If you're looking for a faster Iaijutsu or Rapid Draw with the possibility of no lost actions, try Run & Gun's Gear Access armour mod.

@ Lucean
I didn't write anything about multiple Attacks
ONLY that with Ijajutsu a Melee Attack  turns into a simple Action and with Quickdraw into a free Action

Get rid of the Idea that a melee attack is  always a complex Action (most often yes, but not always)

 so a swordstrike with Ijajutsu and Quickdraw is a free action. the char now has two simple Actions or a complex Action, but he can't attack anymore, because you're allowed to attack only once per Iniphase !

thats RAW

yup that way you can boost and aim!

I disagree.
They don't mention stacking, why do you assume they do? And it's an assumption here on your part, so claiming that it's RAW is maybe a bit much.
It would certainly qualify for "Rule of Cool", but I wouldn't use this interpretation in my game.

@Imveros:
Sadly, Take Aim doesn't work for melee:
"A character may take aim with a ready firearm, bow, or throwing weapon as a Simple Action."

I don't think the adept power Rapid Draw and Iaijutsu interact that way.

The Iaijutsu technique is an action in and of itself that allows the martial arts practitioner to use the Quick Draw Simple Action for any weapon. The Rapid Draw adept power allows a user to employ the Quick Draw action with a reduced threshold and as a Free Action.

The reason I'm opposed to the two interacting is two-fold.
1. The Run & Gun section on Martial Arts clearly indicate that magic and martial arts do not mix well.
2. Rapid Draw directly affects the quick draw action, while Iaijutsu is a separate action for all intents and purposes

That being said, even if you were to allow an Adept martial artist to use both, the effects would be limited to the Adept drawing his sword as a free action and attacking with a simple action. This doesn't severely unbalance anything in my opinion, as the ability to use a an additional Simple Action does nothing to the limit of one attack per action phase, and is of somewhat marginal use as I see it.

[The Wyrm Ouroboros]

... magic and martial arts not mixing well is one of my main beefs with Run & Gun.  An adept with martial arts should kick serious ass.  He should go up a wall like a scalded monkey with a tiger after it, fall from a great height and make a perfect three-point landing with no damage, and all the other things that someone with skill should get when it's backed up by Power.  I understand why it was done, but IMO it was a bad idea, because if paying twice to get one really good trick isn't sufficient to deter someone, then you should allow someone who's paid twice to have a really good trick.

I dunno.  IMO (and game), despite the R&G rulings, I say they stack.  But hey, that's my gaming.
