In defence of Eliot123, from a resto perspective ("here he goes again"), that's exactly how last 2 expansions looked like. Underwhelming, clunky, battling with a design that is not fitted to modern day raids, while producing subpar numbers. Then, a 10/20% across the board hotfix. Rince, repeat.
I'm with you on the HST. I would love some QoL introduced. I would love talent overhaul because there's literally NONE choices involved for a healer. I wish for a mastery rework, but that is the only revolutionary change i think is needed.
Do i agree with all their design ideas? No, but there are ones i can understand - like the one totem per element limitation. I don't like it, i don't agree it's needed, but i can see the viewpoint. But frankly, if a spec requires a flat out buff across the board every tier content OR it drops 40-50% behind, there isn't much you can say to rationalise it.
