1) The fact that you want a stamina bar removed is a bit contradictory to your realism statement. It takes stamina to do ALL things. Hell, an entire auto attack system is contrary to your realism statement. I think regular attack lengths based on weapons and damage and such would be an interesting idea but I don't think auto attack will implement that in any way. (Also, it is not true that you deal the same amount of damage regardless of the weapon you use. That is fully false.)
2) Regular attacks have two functions, not one. Dealing damage and gaining TP. This is realistic as well for you have to get a feel of a fight before going all crazy and doing skills and battle regimens. Manually selecting an attack maybe repetitive, but battle is repetitive. It's only as boring as you make it, however. And personally, watching my character automatically attack while I just sit and watch my TP build up seems boring and repetitive to me, as well as unengaging. I don't have a direct effect on all my character's actions at that point, which makes it less interactive.
3) Why is it hard for you to grasp the concept of second wind taking TP? It's called 'second wind.' As if, while you are in a fight, you get to a climatic point where you are re-energized. You don't think that should take effort? That's generally what TP is. The effort gained by your actions. I feel you need to build up to something like that.
Please stop trying to patronize people into thinking you are the sole proprietor of truth in this argument. People are posting here out of concern for the game that YOU are playing. It's not a sole person's effort to make this game happen, but everyone, including the players. If there wasn't an argument against auto attack then why didn't they have it in the beginning? I'm going to go with Reika on this and tell you that the doors to XI are still open. This is not XI-2 with improved graphics and a better crafting system. It's Final Fantasy XIV.
