Once you disregard your teammates as nothing but meat shields, Kreiger Caustic is pretty great. Dunno what people are talking about when they say his gas sucks. Dumbasses only see the 5-10 damage ticks and think "wowzee that is buns" without realizing it obscures enemy vision and slows, forgets up their aim and disorientates. If you catch them slipping inside the gas it's pretty hard to potato it up and not get a down. ez
