Just made a pretty significant update of the macros I put in page one of this thread. Now have fairly optimized macros for:
Prot Pally
Disc Priest
Marks Hunter
Ele Shaman
Destro Warlock, and
Arcane Mage

I am very happy with the Arcane Mage and Marks Hunter ones, decently happy with most of the others, but disappointed with the Ele Shaman one which I just can't seem to get good DPS out of.
