Loki with a huge disarm, Nekros (always), Nova to soften em up, Trinity for HP and temporary partial invincibility buffs OR Mag to blow everything up with shield polarize. All running corrosive projection to give enemies no armor whatsoever (that's what makes the heavy gunners REALLY hard past 30 mins). You'll need energy restores to keep your energy up, but with a good room,  good players, and RNG's blessing upon you, you can go for a long time.
