I"m mostly a Warlock or Hunter cause of my play style, and I know how to do things against Titans in their Ward of Dawn, but I"m regularly wrecked by Titans with Striker subclass. It just depends on your strategy, like anything. Titans are very well rounded and stable. Just gotta find your grove, the right gear and the right perk settings. I have all three leveled to 29, Hunter is my favorite, but Titans are always a fun class in both PvP and PvE.
