Favourite class and spec to play?

So I’ve been using this great addon and enjoying the community for quite some time now. I’ve seen some amazing macro authors and really enjoyed using them.

Currently I have been levelling and just enjoying the game as DPS and my favourite macros have been

  1. Hunter BM and SV
  2. Rouge (any spec)
  3. Priest (shadow)
  4. Warlock (Destro)

I haven’t really dove into the healing side yet but wondered if anyone could give me pointers on how to heal easily? Or is healing a bit more reactive to the situation and maybe not the best to use a macro with?
