I have yet to encounter one that is “unplayable” but I do question why they even bother with this dated concept. I suppose out of habit to remain coherent with the legacy of PVE?
You THINK you want them to not be there any more, but if you really did you wouldn’t be doing them at all, so it wouldn’t bother you however it is now.
Its basically just there to help undergeared or slow-to-progress characters.
I basically am only doing this one for the rep at this point.
So if they removed the concept entirely, you’d likely just have less gear available to you.
