New card system for AST (why not?)
Why not give AST Divination something AST already had before?
Like with each solar seal, you deal 3% more damage, with each lunar seal you get 3% faster and with each celestial seal you get 3% more crit. This way it won't feel like you didn't use the skill with 3 different seals and got less of this long CD, you will always get something good :)
Also, bring back Lord/Lady Attack/Heal, so you have something to do while Divination is on CD and you don't wanna worry about buffs, because enemies are dying - or the tank is dying - or something.
Also, give back Celestial Opposition its stun, it's much needed. Also Asp.Bene Regen should last longer. Thank you SE.
