Cooldown and animation time

[flipflopmagoo]

With Winds of Harmony and a lot of attack speed the displayed cooldown of Cadence is 0.05 seconds. It is fairly obvious, however, that Cadence does not attack 20 times per second - I count maybe 4 or 5 attacks in a second depending on whether any are magnified. I assume this is because each skill has an animation time that cannot be reduced. Is the animation time universal or unique to each skill? Would it be possible to display this animation time somewhere in game so that we know what cooldown to aim for and we do not waste any affixes on unnecessary amounts of attack speed?
