Stamina Templar's and Templar tanks have 0 stamina sustain unless of course there are fresh dead things lying on the floor.
My suggestion, since all our tanking abilities were taken away from us when Eric Wroebel was just a wee nipper, would be to make Purifying Light's ray or explosion restore a tiny amount of stamina. Not much, a little bit would go a long way seeing as we can't use our own excellent synergies.
Please do it, it still has a mechanic, you can only cast it on 1 target and you have to be right up in the enemies face when it goes off.
What say thee, Forum? OP? Useful? Stop dreaming?
