Basically it comes down to what kind of enemies you're running against.
Mooks are going to have group edge. Meaning that whatever their professional rating is (1or 2 for corp sec, 3 or 4 for law enforcement, and 5 to 6 for elite security and military units), that's how much edge they have to split among their group. Depending on GM, they may split a large group of enemies into subgroups for this (for instance if their are two dozen SWAT members closing in, they might split them into three groups of 8 for sharing), but even that isn't really
overpowering.
Elite NPCs, as in on their own unique, such as rival runners and movers and shakers in the world have their own edge.
I don't really think it should be used rarely for mooks or elites, after all they usually will end up burning some of it just to not be D.E.D dead at the end of the fight (assuming the runners act like stereotypical runners). I think what usually colors this view is that a lot of players put little to no value in edge, never use edge, and view it as a waste because in all reality they've never bothered with it beyond saving a point to burn for a hand of god case. Likewise, a lot of players only see edge as a way to reroll failures. Which is only one single use for it. If that's all it's used for, the rating doesn't matter beyond times you can use it, but using it to add dice a higher rating is always very very good.
I've got to agree with the others though. Saying that it's not worth it because a GM severely cheated with it (or it's believed the GM was cheating with it), can be applied to
any mechanic if a GM uses it to cheat. A bad GM does not make a resource bad. It makes the bad GM bad.
I can slightly see how it can be irritating to be counter edged in some cases, but if you think about it from a roleplaying point of view, there are times when it absolutely makes sense. That Johnson meeting the runners gets his bonus (and promotions) based on the bottom line. Ya, he's probably going to be edging his negotiation rolls since that
is 100% his only role for the company, get a good deal on his deniable assets. So, is the Johnson counter edging, or are the players counter edging (or does it really matter since both uses make absolute sense). Same goes for enemy mages that edge their counterspelling roles. As a sec/support mage, your #1 job is to cover your team astrally. The main part of that is keep astral things from ganking them. Most spells can easily be one shot stoppers if left unchecked, trying to stop them in their tracks makes sense, but it uses up the part of the mook groups edge pool so that's one less edge for dodging, resisting, composure, etc. Then again, this really again boils down to the GM actually roleplaying enemies
and following the rules. If every single mook can edge every single test, you're probably going up against Professional Rating 18 super-borgs and that corp is really skynet in disguise. Time to jump ship or augment up and fight for the machines baby.
