I played WoW for 5 years.. and Rift for 6 months.. WoW was fun to start, it got easier until it was just too easy. Rift was a lot like WoW . Things I like from WoW .. Flying , tame able pets, companion pets, bag storage chatting to other players. Much the same for Rift except no flying.. and loved wardrobe and dyes.
But Skyrim is a different kind of game, I love relying on my own skills and learning best way to get something done, Love the environment, it is more realistic .. I would like better clothes but that is a minor thing.
Would I go back to WoW or Rift.. not unless there were MAJOR changes ( and someway to stop idiots talking to you

)
a hearth stone would be nice.. even on a long cd
