Finaly being able to do old school team based exp grinding again in a modern MMO is going to be very refreshing, questing grinding to level cap got old around 2006, and I don't think I could stand playing another MMO which is heavily quests(wow style) based.

Best times I've ever had leveling in an MMO (and I played most all of the bigger MMOs released since 2001) was grouping up with friends and strangers alike, traveling to a distant location and set up camp, and trough good teamwork the party would soon turn into a killing machine with great exp returns.

Can't wait to get back to that again.
