Proposed AST changes.

[Sovasin]

Also buff Celestial opposition. It's basically the same as whm assize but way less useful. Just compare them. Assize is on 45 sec CD and has 400 potency vs celestial opposition with 250~ n sect. / 100+ 300 in Regen d sect. On a 120 sec CD. More then twice as long cd without any other effect that while assize also does damage and restores mp.

While I think the new CO is underwhelming and boring compared to its SB predecessor I don't think comparing actions in a vacuum is the right way to justify a buff. WHMs don't have Earthly Star, so Assize is their only form of burst ogcd aoe healing. AST's kit already has that niche covered with Star so if CO was as powerful as Assize that would be pretty broken.
