Nobody else does these runs because the vast majority stick to the limitations of PF and DF seeing it as simpler.
We all know for example running any non DRK tank in a dungeon with 3 DPS is objectively better than running it with a healer. That’s just a straight fact. Yet why do 99% of people do dungeon runs with a healer……..because DF says you need a healer. You can up your damage by 6k subbing out your 2 healers for 2 more tanks in M4S and your mitigation plan is tighter but not TOP healerless tight, 99% of people still run with 2 healers…………because PF defaults to a standard comp and strat videos don’t exist for these types of clears by people like joonbob.
The only reason this doesn’t become standard is because there hasn’t been that sort of push that shoves it into the mainstream. If they made a mechanic tomorrow that frustrated PF like light rampart then a creator like joonbob released a new “braindead” strat video where you could sub the healers for 4 tanks short mitting the DPS during the mechanic and also wiping out the DPS check by gaining a free 6k DPS healers would be out on their asses faster than yoshi p could buff succor thinking that would solve the problem. It’s basically a wider version of the problem SGE had in 6.0 when the entire community was like “SGE’s shields are really weak if a mechanic can be shield cheesed SGE will be gone from PF”. In asphodelos there was no shield cheesable mechanics, but DSR had one, you can overmit meteors and just remove half of phase 2. And what do you know SGE got instantly deleted from DSR parties exactly as predicted when it became more convenient to use another classes overpowered skill than it was to continue to equally tolerate both shield healers
The current tenuous state shows how overpowered the tanks are and healers hold on functionally by nature of there just not being a mechanic that shoves PF to actually embrace the change of dumping the healers. But if it comes (and the current trend of how fast and easily we are clearing new floors without healers as time goes by shows it is coming) then PF will just close out healers
PS if it’s true they cleared E4S without healers while current that is an achievement. I was probably a bit overly rude there (especially as I know they are more talented than me) but I genuinely didn’t see something incredibly praise worthy in that M4 clear, it was cactbot infested, sloppy and their posted mit plan really isn’t that tight, it genuinely reads like an Omni blue parsing static average clear
