The real problem with Samurai is that they took one of the best gauge in the game, Kenki gauge, and made it into one of the worst gauge in the game.
During ShB, SAM could spend Kenki for Shinten, Senei and Kaiten. Today it's only used for Kaiten.

The only problem SAM had in ShB was the double midare drifting.
"Button bloat" wasn't an issue and they already removed the actions tied to 3rd eye. Everyone was fine with the 3rd eye change because the consequence remains the same:
Taking damage under 3rd eye results in DPS gain.

I believe the removal of Kaiten would've been fine if the Kenki gauge had another use or was replaced with something consuming the gauge.
The consequences of removing Kaiten impacts not only the SAM hotbar but also the gauge and core gameplay.

I think we should be happy with Mirage Dive revert, it's kinda a proof that they listen to feedback and we should encourage them to continue to do so.
The same goes for MCH, yet I have one complain with it, it's too late.

AQ duration and targeting were already too long during ShB. The fix is basically one expansion too late and EW brought/expanded a ton of issues within the ranged role and more precisely the MCH.
The changes we had for EW are questionable, they bring problems they then have to fix, without even expanding on the job's nature and identity. Crown Collider and Kaiten removal are two perfect examples.
