I agree.

Add the "option"for the player to go into auto-attack mode (FF XI) spam an attack routine until the enemy is dead is perfect for players looking to farm for hours for materials, or who are just not in the mood for fancy fighting for particular reasons. But, as soon as they want to get serious and start doing more complex actions, they can turn off auto-attack with the press of a button and be able to enter commands again.

In the end, you have a WIN-WIN situation where FF XI and FF XIV players are both happy and have more gameplay choices to choose from. I hope they implement a feature like this for us in the near future!
