From the French side, well forum is... dead. Last post on Healer thread was 11-04-2020. so from this source nothing to say.

About the ingame chitchat, I can only share want I experience (I only do Normal, Extreme and Unreal content, no Savage anymore and no Ultimate at all). To summaries, the french community is less vocal about problem. We tend to not complain in group chat but more in private small group so actual feedback comes from a restricted group of person always.

So....
about the heal vs DPS topic > "We tend" to complain when there is a zero DPS healer but keep going as long as the kill is doable.

about the heal balance / difficulty (DPS rotation, OGCD, # button pressed / sec) > "We tend" to say that it's too easy, nothing to heal and just spam 1 skill and refresh a dot.

about the healers resemblance (same base mechanics for all healers with some flavour for certain skill) > "We tend" to complain about that as well but deal with it. Same as for tanks mechanism.

So we basically complain about the same topics but just far less.

Disclaimer : Again, this is *my* point of view from about 30-40 people I hang out with in game. Because I only interact, on a daily basis, with people with about the same general point of view than me (for mental sanity reasons), the sample is not representative at all!
