Everyone and their dog knows mercs are at the bottom of the wz usefulness list but you still find every type being played.
Bodyguard is ok but its not amazingly more useful than Pyro and Pyro is only a bit better than Arsenal. Ultimately they all have the same crap 2 tools to mess with other players which is the core issue with them.
Operatives have so many CCs and escapes its disgustingly useful for staying alive as a healer in a WZ or just controlling the enemy team.
Did i say anything about mercenaries in this thread? I see you know a lot about Operatives and OP they are ...care to share more?
