I agree with most of what you say. DRG is right now at its best state and it's quite concerning that they want to change it. What exactly brought them to think about DRG and not any other job in particular?

It needs small tweaks and QoL adjustments, but certainly not huge reworks in the middle of the expansion.

That said, the latest Mirage Dive change is dubious: while it got rid of the accidental double-weaving, the grace period added is too long, making double weaving it as tight as before the animation lock reduction. At this point they should just revert the change, since they couldn't anticipate that slapping a normal 1s recast time would bring it very close to the original 1.1s of jumps.

This tightness also causes issues in certain encounters like Dragonsong's Reprise, where you want to get an eye at specific points before a boss leaves, but that this change has made a bit hard to get unless HJ is used extremely early.

Stardiver should not get higher potency than it has now because then we start getting close to the territory of "my Stardiver didn't crit so my DPS fluctuates a lot" that plagues so many other jobs. It is Dragonfire Dive that needs a potency boost, or any kind of added effect/role to make it stand out, since it's a bit lacking for a 120s recast ability.

At this point, Dragon Sight should just be merged with LC, making the former a personal 60s 15-20% buff that is an upgrade to the latter and adjusting the potencies/damage of the rest of the kit depending on the choice made. Other people have advocated for the Dance Partner treatment, with Litany activating the eyes due to their shared 120s recast time.

To be honest, with the loss of the tether, the ability lost its main flavor so I'd just rather go with the first option. It frees one oGCD slot in our burst, and Litany would do too much if it gave the eyes to the DRG and the partner in addition to its normal effect.

There's been extensive discussion on the matter of DRG being busy and button bloat in this thread, should anyone be interested: https://forum.square-enix.com/ffxiv/...d-button-bloat.
