There is no extra strategy added to the game by manually button-smashing your basic attacks. Therefore, automating the process couldn't really hurt. Though I hope such a change would accompany various other modifications to mold the battle system into something more instantaneous.

Choosing your action and then waiting for it to happen is just... stupid. Unless you're actually casting a spell.
QFT. Auto attack definitely would not hurt. I would love it as its a pain having to go back to a basic attack every time you do something. Having it be automated would be much better.
