This is my current dps macro on my followers that I use in UK. Im running a paladin and 4 druids. I manually apply treants Moonfire and Insect Swarm along with HOT's as needed.

/assist sbjones
/target frost tomb
/use 13
/use 14
/castrandom Starfire, Wrath, Wrath

This gets the job done. I do not do any positioning for my druids they are just on the standard /follow and as long as they are standing on each other they will hit frost tombs on themselves as well as my paladin out front. I approch the boss from the left side of the table so the skeletons run right to the paladin and I pop Holy Wrath to stop them and keep agro on the paladin and Concecration does the rest.
