IMO a better PLD has these things:

-Atonement changed to a trait and put to 3 stacks and applies MP/DMG to the next 3 weaponskills used.
-Clemency MP increased but instant cast or, ogcd but utilizing oath gauge with MP with slightly longer recast.
-Hallowed buff applied at the start of the animation and not the end.

The fate stay night swords I can take or leave it. Not a fan of the aesthetic but at least its thematically relevant unlike another sword tank job.
