To answer both of you on a gameplay being a balance machine is more about being consistenly able to put out a buff to your party instead of praying RNJesus. Seen plenty if not too many 1-2% enrage that could've been spared by an AST giving balances if only he had drawn one. Had a seiryu few days ago, was helping a friend, ast literally draw'd 1 balance in the whole fight. There was a lot of first timer, we still managed to get it to 1%. Now thats a case on a billion but if the changes were up, that would've been clear.

Leaving this aside, 3 out of 6 cards gonna be useless just because the changes they're making to the combat system.. I'm sorry to hear that this change ruined your class but SE balances things based on raiding content and how consistent a class can get, hell they even giving BRD straigther shot buff with barrage. All the changes in ShB has been made with this in mind. Also ShB isn't up yet don't jump to conclusion at least wait it to get released and try it before saying it got ruined!
