For allot of instances this is doable but there some instance where yeh have to move the tank so if yeh can setup some macro to move yer tank...

One of the problem yeh will have is when the "oh shit" moments happen and something gets away from the tank yer gonna have to setup a taunt macro for each char

But there is no reason why yeh cant do an "RTL" setup

Allot of times this is what I do when the pali has so many critters on em and back to the wall that I cant see anything I'll switch to the healer and heal just so I can see.
