I use all three and I have to say that the titan hammer is super good but not op. Titans don't have a move like blade dance or gg that can get multiple kills in succession. If anything, the new warlock subclass is amazing for close quarters and the Hunter set up right can screw a while team up. Its not about nerfing its about adapting. I've killed solar titans just fine with my warlock. If I see a bunch of solar titans on the other team I'll run voidwalker since nova bomb is a insta kill on them. Hunters can knock them out of their super too. Its about time titans had the lime light. Hunters have had it for to long and I love my Hunter.
