why every FF14 healer is berserk healer

[Azurarok]

With how the game is designed these days, more healing-intensive fights can cause problems since mitigation is a big deal but you can’t trust your teammates in Savage party finder to actually know what Feint and Addle are for. Abyssos Savage was rough partially because of that, and it seemed like less people played healer in that tier than usual.

Sounds like raidwide mitigation isn't something that should be every role's responsibility.
