Legit complaints:

Tempered Will: Too long. Too unnecessary. Needs rework or heavy CD reduction. 60? 30?

Bulwark: Too long. Passive 80+% block rate is really nice but not deserving of sentinels CD, I'd lower it to 120 or 90.

Passage of Arms, this one doesn't really end up being very useful most of the time.The range is funky, you want the tank to face the boss towards the party? The stopping of attacks makes it instantly undesirable in savage due to strict dps checks so when is it supposed to be used? Every attack is already survivable in everything except maybe o4s. And it has this weird delay like Collective Unconsious where it takes like a server tic for the defense to take effect on the party.

Divine Veil : Really good but the CD is pretty long. I'd wonder if it could be reduced a tad to 90. Or to take it a step further, make it cost 100 oath gauge and only be available in Shield Oath so there is weight in swapping stances unique to PLD.

ShO/SwO: This is more of a personal complaint but maybe they could take one off the GCD, preferably SwO like DRK's darkside. And maybe make more risk and reward, such as Shield has a passive 10~20% block rate while Sword has a reduced block rate by 10~20%.
