I don't think you're understanding that I rarely do anything other than press O. Which defaults attack. It has worked really well for me for the entire game, minimal issues.

You can get exasperated all you want, and preach ~the best way to use Aeris~, and quote as many numbers and facts as you want.
I personally do not use her, and find her useless in my "Press X to Win" strategy of playing this game because unless I try extra hard to *steal* her best weapon at the time, or play a goddamned minigame for hours on end, she does minimal damage. Or I can use someone who I find more useful, which I do.
