I was discussing this with a friend and honestly? I think Time Dilation should come back myself. I think having the one cooldown that you either use to extend someone's burst phase or used defensively to extend regens on a player could have the potential to give the class just the right amount of flavor.

I do however, disagree with Celestial Opposition having it's time extension returned. I do believe it should have its stun returned but I just struggle to see SE being ok with allowing the AST to extend their Lucid, Surecast, and Neutral Sect. If the extension only applied to regens and cards then...maybe? but as it is I would just be content with the stun.
