Quick rundown of which melees got buffed:

Samurai (Midaare + Ogi) biggest winner
Monk (Bootshine) second biggest winner
Dragoon (Litany + Lifesurge)
Reaper (Got potency buffs to ensure parity with auto-crit melee)

Of the physical ranged, it's ironically not Machinist who benefited the most from the auto-crit changes, but Dancer who, on top of being able to partner the highest selfish DPS class in the game at 100% efficacy again, also has an auto-crit during their burst.

All of these changes have ended up widening the gulf between melee and casters to an unacceptable degree. Black mage, Summoner, Red Mage and Machinist all need the same parity buffs that Reaper got, Bard to a lesser degree since it benefits more than Dancer in team compositions where damage is more evenly distributed.

Ideally this would be the last set of powercreep buffs in this expansion since the auto-crit changes are a one time occurrence. The only other general system changes would be changing merging Skillspeed and Spellspeed and giving them the auto-crit treatment (buffs the damage of everything they don't affect in some way) but even then this would be nowhere near on the level of the auto-crit changes which are built into job kits vs an alternative method of gearing to crit stacking.
