Who really cares that a warrior can turn invincible for 6 seconds in a dungeon with the same trash pull we've been pulling for like 10 years now? Any class balanced around dungeon content is going to end up in the dumpster. It works fine in raid content and would utilize dev resources to "fix" a nothingburger problem while healer rotations continue to languish year over year. Focusing on taking self-sustain away from a single class isn't really going to solve what people think it will - it'll just increase the number of upset players by throwing the war mains in with everyone else. The time would be better spent workshopping a way to dig healers out of the boring and unengaging hole they've been thrown into. idk why people hyperfixate on tank sustain then turn around and complain about healer dps. You can only change one of those two.
