Enjoy the story, there is so little to do at lvl 70 that many ppl only sub for a month, then unsub til next patch. So you are better off just riding it out if you enjoy the game and actually want to do a larger verity of stuff.

Once 50 hits the story gets immensely better and all the arr endgame opens up. It's mostly busy work but its still something to keep you more than busy til 60 and then again from 60 to 70.

This is one of those games where the journey to level cap, is vastly better than being at lvl cap.
