Job changes you'd like to see in Endwalker?

[Nyarlha]

So that it can be pigeonholed into damage-dealing, rather than functioning as a gap closer?

If it had two charges, Onslaught would be the best gap closer by miles; as is, it's still arguably the best.

"Free" oGCD potency isn't free; it factors into the ppm of the job as a whole and therefore always comes at cost to elsewhere in the kit. A job as a whole may be overtuned over a period a time, but it's not going to be because their gap closers had more potency or less resource cost attached to them. Design for the gameplay you want; the numbers assigned to a particular skill will be ultimately irrelevant except insofar as they influence said gameplay (e.g., through breakpoints by which they change what, optimally, should be prioritized in a given situation).

And the obvious solution to that as already pointed out in this thread is to finally remove potency from gap closers. Let them be what they are supposed to be : utility, and not damaging OGCDs.
