Damage "taxes" deserve serious reconsideration

[CKNovel]

The hort of Nidhoogs second Boss has a phase, where you need to run in a circle. There is nearly to no time to cast at last long spells. The great libary of hw has as final Boss someone, who create range aoe and close aoe. Phases,where meele can not attack (or not strong) and where caster need to run for a short time. Than his run phase, where meele and caster can not attack (at last, not much).

The second Boss of the new pandaemonium has a circle phase, where you need to run and can not use much, spells or positions attacks.

Let's use relevant content, yes?
Nidhogg in Dragonsong Reprise:

All mechanics can be done at melee range.
And this applies to nearly every phase.

As for P6 you can just wait for the aoe to explode and then go through. This mechanics also doesn't exist in savage.
It's not lack of time to cast or keep uptime, it's literally skill issue.

Content in previous expansions isn't relevant anymore. Jobs that got a rework don't have a full kit.
Back in SB, MCH had no tools to control heat in any lv60 content for example.
