I recently ran some trials to see how much haste actually increased my attack speed. The tooltip says that light and heavy attacks should be 30% faster. However, after 10 trials of attacking for 17 seconds with and without the haste buff, I did not notice any real increase.
Without the buff I was able to shoot 15 arrows.
With the buff I was able to shoot 16 arrows.
A 30% increase on 15 arrows should have been an average of 4.5 more arrows, not 1.
I noticed that the haste buff seemed to increase my attack speed for about 2-3 seconds right after I casted it, but afterwards my attacks slowed down to their normal speed.
I only tested this with a bow so I don't know if its working for any other weapons. Does anyone have any comments to add? Should I post this as a bug?
