Which is a good thing. I want a game that is fast paced, you can't be fast paced if you don't build a game around reflexes. If you have to stand still and readjust after every shot because of massive recoil you just slow down the game. And that's not what I expect from BRINK. It was really well done in TF2, no penalty for shooting midair or anything. Playing Scout in TF2 was awesome. A shame that game is getting more and more ridiculous with silly hats.
I don't care about ADS anyway, at least in a not-realistic shooter. It's a nice feature for titles like Bad Company 2 or CoD, but those are generally much slower.
