attack cooldown help

I set a unit's attack cooldown to 50 so when it picks up item with a spell that gives it a 46.2 attack speed bonus its suppose to take only 3.8 for cooldown but when i test it, it takes like 21 secs

What gives?

The attack speed bonus works in a percentage, so instead of reducing it by 46.2 it will reduce it by 46.2%.

so if i set unit's attack cooldown to 100 and give it a 75.5 attack speed bonus then the unit's attack cooldown would be 24.5 cooldown?

Also after doing a small test it looks like attack speed and attack cooldown are 2 different things.

Attack speed seems to affect how fast the attack is done when unit attacks.

Attack cooldown seems to be how long it is between attacks.

Although i cant explain your results i can tell you with almost 100% assurance that an attack speed increase effect DOES reduce the units cooldown.
