While not a popular answer, I'm sure: I can understand making Embrava Refresh instead of Regain, just not for endgame. SCH lacking Refresh and not being able to stack Refresh and Sublimation can be an issue in mid levels. This change would be very nice in a traditional (2008) leveling scenario. Due to endgame content, the currently proposed and thankfully held-off nerf doesn't make sense.

Let's not beat around the bush though! Our post 75 spells and skills and even certain others we complain about regularly *cough Modus Veritas cough* are not in a place they should be. If they were this nerf would honestly matter less. Square, don't put the cart in front of the horse! Fix the already broken SCH abilities before nerfing the one good thing we have going for us post 75. And in case it really has to be reiterrated, this means:
Adloquium being non scaling/weak
Animus not stacking Pax, not affecting real current hate values, etc
Modus Veritas just being a waste even against non-boss monsters
Libra not having any range and an awkward display for values in an Alliance/Party.

Fix this stuff before any nerf.
