why every FF14 healer is berserk healer

[Carighan]

The CNJ questline literally tries to get people to drop that line of thinking.

Yes, many old questlines are bad, news at 11.

Or good in that sense, at least, because how tf else would one deal with varied damage intake without going idle?

The (lack of) frequency is the big issue tbh. If we had near-constant raid damage, both widespread and targetted, then the ability of lots of jobs to produce and stack lots of mitigation would be less of a problem, as it'd only cover some comparatively brief moment of damage.

Mostly agreed on the whole, but...

Constant DoT damage on the group.

This seems the dullest possible way to provide that, especially without a thematic reason for that (e.g., being visibly toasted/frozen/electrified constantly).

360° cleaves on the autoattack timer that damage melee DPS and tanks.

This just screws melee disproportionately. I'd far rather they be involved in de-pressuring the tank by baiting briefly-telegraphed attacks off them (think Caudal Swipe) and the tank autos (or energy built from them to be spent on raidwides) be significant enough to make that extra-role gameplay near-obligatory.

Random untelegraphed line or AoE attacks on people.

I'd argue they don't even have to be untelegraphed. As long as the damage is increased enough to already put (barely buffed) leads in on-demand healing at parity, this would just disproportionately hurt %miti and other time-sensitive preemptive sustain.

Random individual hits on non-tanks.

Sure. Though I'd love for some of them to be more actively interceptible by tanks as well. No need to forgo gameplay elsewhere when we could just tune averages around it.
