You pretty much reaffirmed my point.I think you are on crack.GW2 has a real problem in class balance usefulness in PvE(we are all DPS) but the dynamic quest stuff and PvE exploration as you level up is amazing.
Classes in GW2 in my mind sucked. The leveling which was long and tedious sucked. Downleveling areas to add content sucked. Itemization sucked.
Exploration was great. Group events were ok, but not as cool as public quests from Warhammer. Sure, it was streamlined and there were some neat easter eggs, but the game's PVE is weaksauce.
I can't remember a single thing I did with a group in PVE in GW2. Can you?
