It's a nice ability in certain situations. Like.. the last boss of AK. I FoF on the pull, and once it's back up I Bulwark/FoF and spam Shield Swipe for ubar deeps.
Otherwise, I only use it on the Dullahans/Robed MRDs in AK, or in situations where I'm low on TP(T1).

I don't really think engineering hours should be burned on improving it, but I think it would be amazing if..
1. Removed from GCD.
2. Scale potency with shield block value.
3. Remove Pacify.

1 is to give it a reason to exist.
2 is to not make it OP by throwing on a low block value/high block rate shield, and it gives you slightly more of an incentive to +1 your shield or get the alla shield.
3 is because Stun > Pacify, unless a DRG in your group is DRing stun by leg sweeping in their OGCDs(like they should be).


The main thought process is for us to have something to fill OGCDs, but not make or break us in terms of threat/dps gains. It also increases the risk of being animation locked when you have to interrupt/need to react to a boss mechanic - preventing macroing it into your halone combo and increasing the skillcap on PLD.
