I dislike multi-player mode for pretty much any game, but I understand it, like so many other things I dislike, are part of the gaming landscape and player expectations. Plus, if I don't want to use multi-player mode, I can avoid it. So, not opposed to a future update having multi-player, just please don't make me have to go online to hunt for people to play so I can do some multi-player only dungeon.
Gaming is like porn--it's better done alone.
