I'm doing a Pal 4 Priest team. My priests are on follow most of the time. My pally moves with ESDF and my clones move with Alt+ESDF. If i'm going into a pile of mobs and i want my priests to be at range I'll tap Alt+D and they stop and then i move on like normal then i concecrate and then start dotting on my priests. or you can keep them on follow cause combat dosen't cancle /follow but for some spells like Mind Blast, Mind Flay and Smite you have to be faceing the mob and it helps if your toons are in one place facing your tank and the mobs.

Some times you get a runner or something or a roving pat that comes up behing your priests so you have to turn them. Easy, hit your follow key they will snap to your direction then simply back them up again with Alt+D and keep on fighting. when your done hit the follow macro again and your off.

P.S.
I use F11 for my /focus /follow focus key so it's a little out of the way and gets tedious over time. So I changed my wand macro so that i can use this after each fight to collect my followers and move on down the instance.

/assist focus
/cast shoot
/stopmacro [combat]
/follow focus

this way i can click (A) after each fight but still not worry about clicking it in battle and having all my priests run to me, but a quick click after everything is dead and all my children are in line and ready to move on.

P.S.S> Blacklist sucks if you want to type your password x5 and your movement keys are in your password and you can't /dance either.
