GW2 doesn't really have a trifecta like other MMOs, so there aren't strict tank, healer or DPS roles. In fact, the most efficient (I'm talking speed) way of clearing dungeons is 5 high DPS characters. I mentioned before that I haven't reaaally played for a couple of months, so maybe that's changed by now, but I doubt it. PvP is a bit more complicated, but it's not my area of expertise so I can't really give pointers there. That being said, I don't give too many fucks about the meta unless I am trying to speed clear, so play whatever you want to play. Tankier/healing builds can be really sweet. I haven't tried Druid yet, but I'm curious to see how it changes dungeon runs. Dem heals tho.
I guess my 'main' is my Guardian, who I mainly play bunker in PvP (warning: I am shit at PvP) and standard DPS for PvE. I say 'I guess' because I have 15 characters, many of which I play equally, but she has the legendary scepter and map completion and all that shit so she qualifies as 'technical main character' haha. I also play Ranger a lot. :-D I'm glad they changed how condition damage works in PvE because she is shortbow/axe+torch and I love me that poison and burn damage. Uhh, after that, I guess Necromancer! Apparently I just love all the classes that everyone else hates, bar Guardian. Awright.

@Kehvarl I don't think anyone is arguing, dude! I don't find getting to level 80 on your first character is a grind, personally. The fifteenth, though... ugh.
