The thing we all need to take into account is Square Enix doesn't have all the time in the world to view all the angles. They need a quick solution that will work, not see and hope for the best. Auto attack believe it or not can be easy and quick solution, I do prefer something newer but well that might not happen. They wouldn't of look into auto attack if they didn't think that's what this game needs.

I can't speak for others but for me this will fix many things. I can go afk between fights, can take my time using actions, can read them, talk, check who is online, search for a friend, look to see who is seeking for party and perhaps build one while still soloing. I mean it's endless things this can help with. That's one that they can do, doesn't mean it's only solution. It's no longer what people think is best for them but what's best for the game to be kept alive before it becomes little to late.
