If the problem is 'a bad AST can't contribute enough damage to beat enrage' the answer should not be 'make AST easier so that the bad AST can contribute enough' it should be 'stop being bad'.
DPS checks aren't real until 3/4th floor savage and ultis. If someone fails enrage bc their divination was 1% less than usual or they drew too many range cards I take them about as seriously as the people in TOP that cried 'b-but my hyosho didn't crit!!'. Most of astro's damage comes from malefic/combust, not cards/divi. And if you want more consistent damage you switch to white mage or sage. Same answer I give to people who complain dancer is too inconsistent. Machinist is right there if meta slaving is all you care about. Personally, I play AST for the playstyle, not its balance. I ran nocturnal sect and to quote my favourite ff14 content creator. 'It wasn't optimal, but it sure was viable.' I'm so tired of explaining to people why I play the class, and why these changes completely kill that in favour of a playstyle I could get from any of the other healers. If people weren't good enough to AST at the highest level (because EVERYONE is good enough to play AST at the lowest, bc there's no punishment for not being optimal), they should have gotten better or found a new job.
