Assassin isnt a problem, as long as you can still see the person on the other 95% of the screen.  Personally I dont even use it because id have to give up quickdraw or hardline which are much more usefull for actually killing people.  If assasin pro made you invisible on the other hand, all this complaining might be justified.

I would be fine with it being able to counter assassin IF it was in the assault package. But as it is now, it is horribly easy to get and would just be cheap. Why does everyone think there should be a way to spot enemies so easily?

Get better and open your eyes. Stop blindly rushing and just take a couple seconds to look around before rushing into the open.

One of the most useful perks. In don't have it preset on any of my classes, but I unlock it in my specialist package and it helps so much. I think it helps even MORE on ARs than on snipers because you get a wider FoV(than when you're ADS in the sniper scope) and enemies pop up even when you're not aiming directly at them.

FYI, I deleted the posts because you were trolling and I didn't want to have any other trolls get involved, so don't use it as a way to rationalize a victory. Trolling someone by quoting that they contract themselves when there is no contradiction is pretty lame and you really need to learn english. Please don't talk to me anymore or I will file a harrassment report with the moderation team troll.
