Yeah, I play it occasionally with some friends.I have the heaviest armor and the biggest gun, and I usually wait if there is a stealth element. :D
That's how I used to play it as well. :D Enforcer / Technician, big gun, bombs, and the armour to match.
Then my whole crew went stealth builds and I was stuck outside one too many times. :P Now Technician / Ghost. Stills works out pretty good, just less explosions. :)
