The only thing missing in my game (because I'm thoroughly loving GW) is the chat system. Would be nice to have /say for people around you not being actually what is /shout in other games where the whole zone can hear, for RP purposes...and would LOVE the ability to set up chat rooms for rping like tavern settings and such.
Everything else....can't complain. Loving this game.
Oh, and I've heard several people asking for /who so they can look up other's in game of like level to form group so they don't have to spam for LFG.

You may have wanted to post this in game suggestions. But it is a good suggestion and would be nice if we could set up private chats in game.
