I was just thinking of some changes that might help PLD, and I decided to post them here to see what the rest of the community thinks. I know I haven't done much endgame content, so these changes are based more on what I've been reading on the forums. Please keep the conversation civil.
Damage mods: STR/MND changes to VIT/MND
Cover:
Stance ability. Only one stance may be active at a time. Nearby party members take 10% less damage from enemy attacks. AF enhancement: Nearby party members take 25% less damage from enemy attacks.
Divine Veil:
Divine regen is placed on the PLD as well. Otherwise, it is the same as it currently is.
Outmaneuver:
Stance ability. Only one stance may be active at a time. Greatly increases block rate and damage mitigated from blocks. Restores TP with each block. GLA trait: Adds MP restore with each block.
War Drum:
Instead of dealing damage, it greatly increases the attack of all party members (includes the PLD) in range. Generates massive enmity based on the number of allies affected.
Holy Succor:
Heals PLD and all party members near it. The AF enhancement remains the same.
Reprisal (note: for level cap rise):
PLD spell. Buff type. 20% of damage the user takes is dealt to all enemies nearby for the duration of the buff. Generates a large amount of enmity with each pulse.
Sacred Knowledge:
PLD trait (not GLA trait). PLD can block most magic attacks with a shield (applies to both autoblock and skills that force block).
Divine Defense:
PLD trait. PLD takes 10% less damage.
