u do know that some skills have an attack duration of their own right? fighter has it with the needle skills for example
there's a diffrence between attack speed and a skill animation, the skill animation speed in general is fine, but upon using auto attack, the skill animation can be ignored and a cc effect will not apply to your opponent. The attack speed was the problem, where fighters would use thunder and blits fist (huge increase in attack speed) and you would still have the same amount of delay time between two auto-attacks combos. I still can see this is not fixed yet.
