I'm really liking Guild Wars 2 at the moment. I've participated in both beta weekends so far and the personal stories I got so far with my different characters seem promising.
There are a few weapons you can switch around with too, depending on compatibility with it. With each weapon/off-hand weapon combos, you get a different set of skills to work with. Little to no grinding, all leveling is done mainly by quests. Plus, you gain new skills by using the skills you already have to unlock the new ones so you don't necessarily have to level.
You should definitely check Guild Wars 2 out if you're looking for an mmorpg outside of aeria. Yeah, you do have to pay the $60 for the game, but it's basically free after that.
