I don't care if I can still talk to them, I won't see them in the world. If they add cross server friend lists/queueing, then I'm still playing a lobby game, a FPS, D2, etc, and not a MMO. How boring.
Not knowing ANYONE on your server in WOW is a horrible feeling. In vanilla I knew almost everyone, even their alts. In WOTLK I pretty much didn't know who anyone was at all, because of dungeon finder, cross server bgs, cross server arenas,faction changes, server transfers(3 day cd really?) name changes, etc. Might as well not be a MMORPG at this point.
Too bad this is what the new gen of gamers want, you know, that gen who plays FPS on their consoles(LOL), and other retarded things.
