Very true. I liked much more the frenzy mechanics before auto-attack...IMO they could keep AA...not a problem at all...many people like it...but they should keep basic attacks with 2 sec delay in exchange of increased slot cost, forthose that would rather keeping their own battle pace...and if you ask me "why 2 seconds?" i'd say "because the fastest AA has 2.3 delay"...and, just like any game that offer the option of using somehing automatic or manual, the manual usage, exactly because is much more complex and require more effort, would always have an improved performance against the automatic usage...any game you see this, from racing to MMOs, if you can choose the automatic will bring flexibility to user and the manual will bring performance. I don't see why FFXIV can't be like this...
Its what i keep repeating to dev team over and over and over again...adding features will always offer better results than fully replacing them.
