yeah but combined with the invisibility I get from crouching in a spot and from hitting people with my melee attack, I am constantly going in and out of invisibility and the fact AI can't see me is really helpful in reviving teammates and escaping bosses and such. It is also a great way to trick peoples radars in order to relocate.

Another thing to think of- while one cannot automatically regenerate ammo with PaT, it helps with ammo sweeps around dangerous enemies.

You have more experience with one than me though, because I know you have/had one. So we will just have to see!
