Making it non RNG will make the job way too strong and no one would pick any other job in raids.
I'm glad they let Ewer and Spire as AOE cards as those are pretty common.
Thanks to the buff where some skills are 30 seconds, I don't see any problems with it being RNG right now.
I'm also glad they fixed AST Noct stance to where I've officially shelved SCH for AST because I wanted to be shield AST to begin with.
Too strong or not, I'm having so much fun with AST than I did in 3.0 so that's my thing for this topic. Finally fixed.
