If we remove all PLD utility we also need to make everything else equal, PLD will need to be buffed in AoE and get a gap closer, also the defensive cds will need to re-adjusted as PLD have longer cooldowns. Eventually you will end with 3 classes with identical skill just with different gear and a far less interesting game.

I think that PLD utility will only make a difference in the most cut throat progression meta in very rare cases these skills can help prevent a wipe. If a raid is relying on clemency to get them through a fight they are unlikely to succeed.
