There are no extremes here. You can undervalue the scope of the change as much as you want, but that is irrelevant. The fact remains that it does take away from the involvement, and that is a reason enough to not change the system.
How you somehow figured that "I think the battle is completely automated" from this, I have no idea. It does not matter whether the whole battle is automated or not, it does matter that a part of the battle is automated when it does not need to be.

The only people thinking in extremes here are you and Currahee. "It doesn't make the whole combat automated" is an excuse at best, when the battle does not have to be automatic at all.
