Healers need an overhaul

[Hezhi]

im not a healer by any means (and ill be honest havent read the hundreds page befor)
but i find it very VERY interesting that NA/EU community argue about healer not having enough dps
while japanese community literally does that

solo heal a ultimate !!! by just healing and not dpsing

again i am not a healer, but maybe just maybe most people got the job wrong ?
i dont mean to step on ppls pride or be rude by any means

You're not being rude man, it's an interesting point!

The issue here is, most content is designed around having 2 healers. In the video you linked, some mechanics are supposed to go exclusively on healers, and if there aren't 2 healers in the group, the mechanic will go on someone random, making the fight harder than it should be. For an example im more familiar with, in the damage in P4S can relatively easily be solo healed, but during the fight you'll get a mechanic called Pinax where there is 2 untelegraphed stack AOEs that go on both healers and requires the party to split into two 4man groups to soak. If there is only 1 healer in the raid, then one of the untelegraphed AOEs will go on some random other person. If that random person is stacking with the only healer in the group on who the AOE is guaranteed, it'll just kill them both and everyone stacking with them. It's basically 40% chances to randomly wipe due to that one mechanic, because there's only 1 green guy in your group.
The content simply is designed with 2 healers in mind, and as long as it is like this I believe people don't get the role wrong in the way you're describing, and videos such as the one you linked are outliers, as it only added more RNG to an already insanely difficult fight. Your average raider won't wanna put up with this lol.

Also, in the video you can observe that even solo healing a fight as difficult as busy as this, this healer... Also DPSs a lot. You can observe them casting a lot of Grav/Malefic during downtime when his team isn't receiving any damage...
