1. A lot of hunters and warlocks are using only new subclasses because it's fun using new content. We also have to max out subclasses. It's unfair to tell Titans to stop using a new subclass and leave the other two alone. It's not our fault sunbreaker is good; you can't seriously tell us not to play around with new content. 2. I've seen striker Titans in the crucible. 3. Nobody used defender in pvp anyway.
