fef, thanks for that, the focustargettarget looks good and I think putting the dps macro on the same keybind as the heal is a great idea.
Smoooth thanks for the tips, I loaded up Jamba and set the health warnings on the slaves to match the keys I have to press to heal ie:
If the shammy who's healing key is 7 needs a heal I get this raid warning: 7. HEAL SHOEZ - takes the thinking out of it Also coming up
with that was after several wipes lol.

I tested my new setup in HGrundrak as I know the instance quite well. Sladran and the rhino guy were fine, Eck however caused 4 wipes
until I go the hang of it and implemented the health warning change.

Also noticed that for some stupid reason I'd unbound chain heal, which was a bit of a shock and caused one of the wipes >.<

With ES and my resto shammies 389 tick on healing stream totem plus 2 other HS totems ticking for 220ish he rarely needed to heal the tank
on the rhino guy, the tank always semed to only go to about 95% and was then quickly topped up.

I'm impressed so far with using a resto shammy but need it to do some dps so am going to implement fef's dps suggestion.

Thanks for pointing me in the right direction
