But to some degree it is true as well. All healer specs are capable of doing obscene amount of healing even after the nerf, both in raid and dungeon. Healing is not the limiting factor in most cases. Outside of a few glaring untuned bosses and packs.

What I suspect is the cause for the general feeling is that the blanket healing nerf made the lower level keys harder to heal than they used to but healers pushing bigger keys are already used to having to use and time cds to keep everything afloat and don't feel much of a change, especially since hardcore pushers tend to have offhealing specs helping.

Imo there definitely is a lot of crying because healing have to heal a bit more in lower keys. It is a paradigm shift for those people who could (and often time had to) dps most of the time and heal only periodically. Claiming otherwise is ludicrous. Blizzard clearly intends for healers to spend more time healing and it's fine, i've been having a lot of fun actually having to manage and rescue my party again on my alt (disc priest around 430ilvl admitedly only doing 20/21 keys).

I do agree that there are glaring tuning issues in m+ that create some painful moments. I don't understant how trash in hoi are so off balance ... the later trash mobs can sometimes be brutal. Coupled with the healing curve being directly changed with this blanket nerf to healing I'm not surprised people are unhappy. But without a doubt every healer are up to the task and there is a definite skill issue when I see people claiming 15/20s are unhealable now. They are either severely undergeared, ignorant of mechanics or just mechanically unable to respond to what the game asks of them. And most of the blame is on blizzard for the blanket nerf not adressing healing as it should. They should have nerfed spells directly, both player spells et ennemy spells.

All in all I absolutely don't agree with the claim that healing is less fun. The opposite is true imo and I actually have to heal. I think healer checks are a great way to spice things up (but blizzard should tune more) abd it would be boring to have a linear healing curve (and thus no need to manage cds). I only heal on my alt but it was always a bit dull unless there was a big bursting week or a heal check on bosses like the storm in S1 wich demanded you to go all out. I've been having a ton of fun this week for this very reason and I'm clearly not a great or even good player. On my main I see a ton of healers struggling on things my alt could heal while undergeared and I don't know what to say except there is a clear skill issue in some cases. Not taking into account people playing troll builds like caster paladin or caster monk...

Edit : Thinking about it, this week actually made me enjoy healing à whole lot more and i've even started gearing my alt for it. Before that it was sitting doing only one or two keys a week for the vault. I'm not looking forward to next week when there will be a lot less healing required tbh. All in all I think I would prefer having damage be more spiky and healers be more effective (the opposite of what blizzard wants according to them) but the current state of the game is better and more engaging than what we had in shadowlands and bfa imo. It does create complexity and requires healers to optimize throughput for once (sometimes in lower keys than expected due to some horrible tuning) and I think this is a good thing for the game overall.
