Regular PA is easy to differentiate, White HC/Blue Melee Tank PA, Grey rifle/Blue pistol Spy PA, Red Aggressive/Blue Passive Monk PA, Silver Pistol/Blue Rifle Private Eye PA.

I personally think the WoC PAs look awesome but it'd be cool to see the different classes.

How about changing the white "piping" on the PAs to reprsent their respective classes.

So:

PPU = Blue
APU = Red/Golden
Pistol Spy = Blue
Rifle Spy = Silver?
Pistol PE = Silver?
Rifle PE = Blue
HC Tank = White
Melee Tank = Blue
