Scroll Advice

Hey all. Thinking of coming back but need input on selections. I currently have an 85 Shaman (and myabe 85 warrior) on my account. Both have little gear. I have also played an 85 hunter (was using friends account). My question is, what class should I take to 85? I was thinking of Druid or Warlock or get my own hunter, but want advice from people who are more into the MoP scene who knows better what is coming down the pipe for each class.

Thanks wowit
