People completely against Auto Attack are thinking way too much FFXI. The difference between FFXI and FFXIV is the fact that a class didn't have that many abilities to begin with and TP generation was slow - in this game I believe what they'll do is turn some normal abilities into TP generated ones, such as Sentinel for gladiator for instance (although not necessarily that one) and keep TP generation fast and furious to the point that you will always be involved in the fight, you wont be always spending TP on weapon skills constantly because you have other more important uses for it, and you wont just be sitting there doing nothing but auto attack.
