RuneScape. It sound ancient but it has made many advances to bring it up to date. Voice overs, new animations, abilities for more active combat, much better music and weekly updates.
I also love the quests. No MMO has ever done quest like RuneScape. They are involved, the dialogue is great and the environments are very varied. The majority of quest actually feel important (except for some of the lower level ones) its none of that "fetch me 10 board hides" bullshit, but actually have a story and unique dialogue. You can't grind on quest, so it gets you to do them for the actual story or unique reward. Some of the newest quests have been some of the most memorable quests in any MMO I have ever played.
Quests is what really keeps me coming back.
