When we look at how DPS checks are balanced with enrages and burst checks in savage, is there any reason not to balance healers as strictly if they only had a healing kit? Would it really be unfair if at below minimum ilvl healers would need 90%+ throughput to keep up, when the DPS classes are expected to push at that level anyway?
If they wanted to make healers more healing centric, I think they should do that. They can't really get rid of the offensive side of healers though, since gear progression will increase that portion, and it would result in idle time for the top players. But increasing healing requirements across the board outside of mechanical bursts wouldn't necessarily be a bad thing. I do think that would require making the healing toolkits more interesting though, as the bread and butter heals are still just the basic HoT + cure/benefic/physick, which is incredibly bland if that is what you're required to spam for the majority of the time.
