If the stamina gauge worked how it does in FFXIII then that would be a million times better than what we have now, also FFXIII had a quick toggle auto attack so they would have solved both problems in one go with that system.

In FFXIII you could combo/que different moves and then unleesh them when you wanted for a string of moves or you could just launch single attacks quickly when needed, it worked perfectly and when I first heard about stamina being used in FFXIV this is how I imagined it would be used, that is not what we got however.
