Any mmorpg suggestions ?

Hey, my life kinda sucks now. I need a game to relax and forget my problems and Dota isnt helping. I'm looking for a mmorpg with many online players, decent graphics, big world, lots of character customizations and i dont want to be forced to battle all the time. I would prefer there will be no sci-fi objects e.g. aliens or monsters, but its ok if there is. Any suggestions ?
