PLD level 100 skill:
- Upgrade to Hallowed Ground
- Same effect and CD as Hallowed Ground, but...
- Duration lasts twice as long and cooldown ticks down twice as fast while you're in "walk" mode
- Name: Endwalker

Seriously, though, IMO PLD is in a great spot. Vastly better than pre-rework. The only minor things I'd like to see is upgrades to the 1-2-3, most notably to Riot Blade, and an upgrade to Goring Blade to make it less thematically jarring.
Seriously, the rest of the combo is perfectly fine, but the jittery animation of Riot Blade makes it look like you are trying to perform the thrust with a dislocated shoulder. And why does the job have "Goring Blade"? This is minor in the extreme, but it's been a niggle for me since HW. The shiny royal/holy knight going around disemboweling people never made sense to me.
