The game is running into a rather unsustainable situation.
Tanks (aside from warriors) really seldom need healers.
DPS that fail mechanics need healers, but they die instantly at a certain level.
There do exist some heal checks, such as the entirety of halls of infusion from start to finish where the healer is given an artificially difficult job.
From my limited raiding experience, raid healing seems more in line with what I’ve been used to in the past. Damage goes out, you heal it. Tanks get beat up with their endless every fight has tank swap mechanics life-you heal them.
IDK.
Just seems like healing is either completely unnecessary if people are playing well, or you have to have it because mechanics exist soley for the purpose of justfying the existence of healers.
