New Operative Buff: Camoflauge

Camoflauge allows the user to vanish off of an enemies radar and screen ( The Aura around you when scouted or carrying Objective) the moment you become out of sight from the opponent.

Without the Buff you will have the usual effects of being able to be chased down thanks to Radar and staying on peoples screens a little bit longer when carrying objectives.

So what do you guys think? Would it balance the Operative out a little more?

I think I'd give them just enough of a boost that they don't 'need', but also wont really make them overpowered. So my votes on yes.

EDIT: Don't think it should be aloud when carrying an object, same as with Disguise.

It just makes your invisible on radar when somebody on the other team doesn't have a sight on you, if the other team has a sight on you, you'll still appear on radar/Objective Aura.

So, would buff be a last-until-death buff? Or does it have a time limit?
