The only reason I'd be against cross server gameplay is.......what if I meat a friend there? and I wanna play with him/her on the reg. Now i can't cause we're on two different servers and we just happened to meet via fate or random matchmaking lol. Really the only reason. And honestly the lone wolf who doesn't have friends can shout in uldah for a group, or they can add party flag function with dungeon options. I hate that lone wolf excuse, its an mmo.
