Divine Veil

[Enkidoh]

Divine Veil makes better sense if you look at it from the perspective of PLD's very image - a selfless knight putting others before themself, but, on the other side of the coin, they are also dependent on their teammates (read: a healer) to back them up, hence the proc requirement from a heal (although the PLD themself can self proc it anyway by simply casting Clemency, there seems to be resistance from players doing this, something something "breaking combos" yadda yadda "overhealing" blahblahblah), and how it only affects their party members not them.

GLA/PLD also has a number of potent self defensive buffs anyway (Sentinel, Hallowed Ground, Holy Sheltron, we also used to have Rampart as our own ability before it became a tank role ability, and Foresight and Protect as crossclass buffs before they were removed from the game).

And although there is a lack of 'easy party wide' defensive buffs with PLD, we do have buffs that protect others at an individual level (Passage of Arms with it's conal shield, Cover to a single person), so we don't exactly lack for defensive options, they're just more situational and require... um, foresight rather than rushing around mid fight and popping some easy defensive ability with no further thought.
