Making or breaking of the agent profession isn't the discussion (Start a new thread about it if you like in the agent section). I'm not here (and I guess, neither are the others) to impress you but apperently you're very selffocused in a thread that's not even started by you.
"Remove CH form Agent Shadow/Mimic Line"
Excluding one more nano from the FP ability never solved a problem it will just narrow down the options a player has. Playing only in FP doc because of CH should make you consider rolling a doc and with the support in pistol perks you might even do better.
In some perspective CH looks OP but on a larger scale isn't.
