I was never advocating for completely removing all direct heals from Restoration druid. All I said was that compared to Legion, our play style has deteriorated greatly. I remember being able to complete high keys while keeping Regrowth cast to a minimum and having a lot more downtime to help with DPS.
I don’t really agree that our play style has deteriorated in mythic+ specifically. If you had said raiding, I would agree to an extent, as to me there is less flexibility to choose talents and gear in raids than there was in legion (or at least less flexibility that feels competitive).
In my experience in mythic+ the reason we were able to keep regrowth casts to a minimum in legion was because mostly we could just use rejuvenate/wild growth/efflo/LB combined with CDs like flourish and EoG to cover most damage. regrowth was mostly in rare circumstances like when someone was getting particularly blasted. We basically never had to regrowth a good tank because a good tank was their own healer in legion. This was changed with the new direction they took with tanks as opposed to a new direction to us for the most part, tanks just need more dedicated healing now.
In terms of having more downtime, of course we had more, between legendary shoulders (if used) and persistence relics we were sitting at rejuvenates that could last up to 31 seconds and for 22 seconds baseline, with the current duration of 15 seconds (16 with AL trait) we would need to cast 50%+ more rejuvenates to have the same coverage (though having the same coverage is not really going to happen). I agree that this feels bad after having had the long duration, but I don’t think it is reasonable to expect our class to play as care free as it did it legion, we didn’t even need to be proactive in a lot of cases, we could just default to having 6+ rejuvenates out on our party the whole dungeon.
Maybe your legion vs BfA experience was different but for me the change felt more like a healer style change than a specific resto druid style change. Healing in general feels more frantic in dungeons because they all feel less powerful, 15-20k hps overall for a dungeon feels pretty solid currently, with people having 150-175k health without stamina, where as in legion I was seeing more like 1.2-1.7m overall hps with a health pool of like 6-7m that lower ratio leaves things like quaking (that felt trivial in legion aside from a spell lock) feeling like a pretty considerable damage taken increase that leaves us with much less time to dps.
I could write volumes about which style of healing between legion and BfA feels better, but I don’t agree at all that the style has deteriorated, I find myself using more talents and making more hard choices than I did in legion, which to me is a plus. In legion most of the decision making was what gear to wear, with the actual spell casts being rejuv either way. Now you wear whatever one size fits all gear you like, and have to choose between spells, that fwiw all feel kind of weak in comparison.
Last thing, to your point about living seed in your previous post, I loved living seed and would also much rather have that back than healing touch, living seed was an interesting mechanic that made our direct healing feel much more druid like.
