I never thought of driving the raid with the off tank, but that actually makes more sense than with the main tank since the ot will usually be moving around more.
I'm setting up the G keys to do exactly what you are talking about, one for each character, either that or just a simple /heal [target=focustarget] macro will probaly work in about the same time and will save me some keys if i need them.

Thanks for the break down, i've got a good idea of where i need to go to get this group in line, but it's like starting over somewhat going from 5 to 10. But i'm always up for a challenge, which is why we all started boxing in the first place.

Thanks again
