i actually played the original beta for this earlier this year but kinda forgot about it until they sent me an email telling me to come do beta 2, but this game Wish might be just what you're looking for:
first link is the game homepage and the second link is an extensive article examining the skill system and the no-"treadmill" gameplay
it's got a really nice set up, enjoyable graphics and races, and a bitchin sound producer. also there's only going to be one server. they're setting up some new kind of server that can accomidate tens of thousands of players at once in a continually changing game lead by a full-time team of live story advancing members that continually bring new experiences to the players.
there are no quests that can be done more than once. there is no level building. you get skill points based on completion of tasks, rather than killing monsters.
it's pretty fun
enjoy it; i did
