The removal of RNG has totally ruined AST's flavor.

Honestly, they passed up a perfect opportunity to keep AST's flavor while simplifying gameplay and making it more engaging to play in between healing.

AST cards should be its primary DPS mini-game, not its healing/support skills. It has access to plenty of consistent healing/support through its time magic spells. What it needs is something more engaging to do for DPS downtime, and random card draws are perfect for that. Varied DPS with minimal opportunities for spikes may be frustrating for DPS classes, but it would be perfect for a healer class that isn't expected to do much damage anyway.

Make AST RNG again. Make AST the pure-heal DPS counterpart to SGE.
