Guild Wars 2
Less grind, the only grinf you will ever find, is trying to get cooler armor, max stats armor are rather easy to acquire
Structured PvP is amazing, really fast paced and dynamic (you can dodge around, cast spells while moving etc)
and it also offers WvW, which is 3 servers fighting each other on 4 huge maps, with hundres of players zerging and trying to take over the other servers castles
Great Guild system, which they are working even more on after release
and the way you do quests is very different - they got a Event system where the quests tricker by themselves, so it feels organic and very dynamic
and there is a personal story as well that make your character even more unique
