Pacification does it work on bosses?

[Synestra]

I could see Riot Blade, Shield Swipe, and Cover all getting changed a bit.

I think Riot Blade is fine as it is currently but SS and Cover needs some fine tuning, either give SS small enmity modifier or make it off-GCD skill. What Cover needs most atm imo is increased range but having MDMG reduce in it would also be neat to have(it should also scale by your stats and not the one you are covering), also Stuns should be off-GCD(like lancers for example)for all classes that has it not just for PLD's to make interrupting more userfriendly and fun(also silence and stun effect should apply when you cast it and not after animation is finished).
