I once would have agreed with this but I don't necessarily think this is a good compromise.
First and foremost because the number of people that wouldn't necessarily understand the implication, or even the actuality to many of these systems (e.g., two-minute meta/rotation) - Which is a very, very big problem in and of itself. - As these answers can come from people who don't understand it can have implications on those that are most impacted by it. Even if you are to also provide an "Additional Comments" box for people to expand. - [Edit] Just to add, personally I would be inclined to ignore the question on the state of healers in and of itself (I can only speak of what devs have responded to when prodded to this) - But not everyone would appropriately abstain when they should. Sure, I level them and sometimes use them in dungeons, and I might find them OK, but I don't really think answering it would be fair on people that would be impacted far, far more than I would ever be by it.
I would even go so far in to say that the problem isn't necessarily getting the feedback - It's '1) Actioning that feedback' and '2) the consideration of the fact there are still other players regardless of what the feedback might say.'.
The biggest problem in many cases is they see a particular piece of feedback, and in some cases they also action it, and of quite a few they action, they completely forget that there's still another group of players on the other end of the spectrum. So they're eagerly trying to address that feedback, without factoring in the wider scope.
Like, they have stated they have made many changes because people have complained that things are too hard, or take too much time, but they have literally gone so hard on this, that they've actually lost sight on what people were saying in the first place. Much so to the extent that "Things are too hard" has been arguably substituted into them just outright removing anything that would cause a player to make a mistake. It's the same thing with the relic - People complained it took too much time or that they have to engage in a particular piece of content, even after Shadowbringers - So their response was to turn everything into a Tomestone pump and dump which isn't even greater than the tomestone cap.
Don't get me wrong - It's all nice and stuff, but none of it matters much when it's the actioning it that's actually the part that's flawed. There is no "Perhaps there should be a middle-ground here" in many of the instances where they action feedback - and I don't see this being a cascade for change of that, they just genuinely need to reflect harder in quite a few of these instances.
Let's take the 'Healers' question for example - It doesn't really matter when there's already been a record to say "If you want harder healing then go do ultimates" - It doesn't actually address anything.
