(Id also think it was great if the pose changes between stances I.E shield oath is shield up and blocking)
Secondly make it seem more akin to a PLD( or knight for Japanese version). Make it so cover now absorbs all dmg that the targer take but before mitigation. Allowing for a wider use.
Make it so he can now apply more debuffs allowing the party to do more dmg that way. This would come at the cost of dmg but it\\'d make the PLD feel more like a knight protecting their allies.
These changes would make the pld aquire a more seperated role from the tanks and may introduce interesting game play for them 2/2
