Post the tank you want the most and why when you play as healer
(blue or red thing for the moment)
just personal choices.
Mine as a sch is War, with all the buffs up i see Physick feel no shame againts a cure II, and when he has only his hp buff all i need to do 1 lustrate which has no cast no cd(that 1 sec seems like 0) and well managed, you always will have stacks up and ready for recharge.
