So true. Especially the teambuilding thing. Not just that, but there should be some kind of teambuilding interface for the people in your group: a popup csreen which lists the players !with the powers they have equiped! and a chat interface so you can quickly get your group set up with some good complementary powers, instead of asking 'hey, you got [skill x]?'.
As for the expnsion...nope, didn't grab me. A Middle eastern setting....meh. Although if they implement massive pve + exploration, you might find cool ruins, and quests relating to those found locations...but GW was never really about that much, which is a shame. But it does seem they've focussed on pvp in this expansion...again, just like the last one. No new races (it would be cool to play a beast race...would be cool for pvp /and/ pve), no interesting realy new environment...just a middle eastern derivative. Hell, why not try an african setting? Some cool, primeviel setting...aboriginee would be cool also, with the whole Dreaming setting. Oh well.
