I didn't really like the single player games, and I don't know if this is going to be an improvement. I don't mind paying $15 a month for a game if it is good.
With regards to the character creation ... see all that before. I think it should just be taken as standard options for new MMOs.
I just hope that the gameplay is exciting, with strong action combat, and fluid movement. I played Skyrim for a while, but it always felt like it was a bit slow, like playing underwater. It was nice customising spells, but they must really build on that in the MMO.
