I find this interesting, because I play as a Warlock and I can take on other Warlocks like they're jokes unless they have an obviously bigger gun. I.. have markedly less success with Titans and Hunters. Perhaps each class is strongest against itself? That was my theory, at least until reading some posts around here. Not so sure now. I have noticed now that I'm thinking of it that I constantly get 1-hit by Titan punches, but can remember no instance of it the other way around, even with melee ability. Hunters seem to have the best abilities at ranged in PvP, what with invisibility, proximity and cluster (and cluster prox) grenades and a predisposition for snipers. I usually do best as support/sniper because up close I get wrecked, even sometimes when I get the drop by a couple seconds and don't miss.
