Star Wars: the Old Republic

I know that WOW is the grand-daddy of games...but to be honest I think that Blizzard does a poor job of running it, and I find that the game tends to be mindless most of the time. I want some challenge and some variety...not the endless grinding that WOW seems to be. There's a reason that I didn't end up progressing past level 30....yet made it far further (in terms of hours played) with DDO.
