I would take White Mage's Separh Strike.


Jumping at enemy target's face is a super fun thing to do in PvP, and would be an effective gap-closer.



I don't mind if SE turns it into a GCD with less potency than Glare and long cooldown for the sake of balance.



And before someone gasp "Lost Seraph Strike", I play enough Bozja contents that I have all Resistance weapons lining up in my retainer's inventory. I love that skill and use the heck out of it, but I wish to see more of it outside of an older content.
