I don't mean to be negative here, but I have to chime in. The last I played the game, which was about 1 week ago, there was still a little issue with the targeting. That targeting reticle for attacking enemies (not NPCs) sometimes is tricky to control still. It jumps around a lot and doesn't always target the enemy you're selecting.
This would create a problem if a 'auto-attack' option was enabled because I'd probably get into a battle with an enemy I wasn't intending to. Then they get all aggro on you and start giving chase.
This has been my personal experience with the game. Has anyone else had an issue with 'janky' enemy targeting?
I think that should be addressed first, then the game should at least give you the option to 'auto-attack' if it was there before in FF11.
