on my shamans, it heals the member being beat on by the focustargets target. Also if you're targetting a party member, everyone heals that member, and if nobody is targetted then they heal themselves. I have yet to have any problems with this macro.
I like this setup i think ill give it a crack.

Currently im using a basic :
/cast [target=focustarget] Healing Wave
which comes from all 4 shamans downranking there HW. Later on ill change it to 2 LHW and 2 HW all downranked.
I think this way even subject to latency i may not have the problems im having now.
Thanks for the advice!
