Grouping is one of the unique selling propositions that MMORPGs have to offer over other genres. Plenty of other opportunities for single player, online play...

If developers of these games don't take advantage of it, these games are no better than Quake or Unreal, etc. The idea that you can have massively cooperative gameplay is unique to this genre...

My current biggest fear is what Bioware is doing with Star Wars The Old Republic...

Oh well, I guess I could always just take up model rocketry for a hobby instead.
