I honestly think it’s not about redesigning healing to make it more “enjoyable” as Healers are already different and quite versatile. I think what is rubbing people up the wrong way is that a Healer MUST at the very least go 3/3 with the other healer to just maintain rating which given how random solo shuffle actually is (as Beware has said) makes even that hard.
Even Gladiator players are taking 10 times more games to climb the ladder as a healer than they are as a DPS cause of how the rating is being supplied as a healer. That is turning ALOT of healers away from solo shuffle, if they sort that imbalance out the healers will actually play it.
I only play till I get my 3/3 then don’t touch it again for the week purely cause of that single frustration.
