I do agree with the idea of having all heals grant Sacred Sight unconditionally, in the average run I doubt you'd get too many these days, I'm just a little concerned about those really bad times when a tank doesn't tank. It could be neat to have a healing mechanic with SS, maybe two, I'm thinking maybe a 10% increase to healing potency per stack and a big AoE heal+mit spell you can use a token on so that those tokens remain useful, even when you're locked into heal spam through no fault of your own.
