Did Hurricane's speed get doubled in the BB patch?

Correct. Booster does not affect the firing delay between each arrow, but it does increase the speed of the strafe animation for the character.

I dont understand that. So whats the point of booster then if you fire the same amount of shots in the same amount of time with or without booster? Unless "strafe's animation" is longer than the firing delay, so an increas in the animation speed makes one fire more arrows in a set time?

So basically you are saying that all booster does is increase the animation speed of skills and not the skills itself? This in turn makes it feel like our skills are faster, but in reality the firing delay of skills have a hard coded "maximum" speed that is unchanged and can only be reached under certain circumstances?
