alot of pages here now, not sure if this was already posted or not (sorry, I'm too lazy to read thru 16 pages) but a here's a simple macro I use on all my toons on my team

/target (toon)
/cast Cleanse

just change the (toon) to whoever you want to cast cleanse on for each account. just make sure that toon is not on the same account as that pally. here's an example.

my main (tank) targets slave 1, then casts Cleanse. Slave 1 targets Slave 2, casts Cleanse. Slave 2 > 3, then 3 > Main. that way each toon targets another in the party and pops Cleanse at once, like a full circle of healing. I have this macro on the same key across all toons so I mash it when I need to. another helpful tip is if you run an all Human Pally team, put "Every Man for Himself" on round robin, so incase your whole team gets MC'ed, Feared, or Stunned, you can hit this once for one toon, then mash the Cleanse macro. It' will free one, that one cleanses the next then they just make the circle. Very helpful in PvPing. can be done with any trinket that offers the same as Every man for himself.
