zerker or scourge ?

k this what happened

i was dueling with my pala vs another pala

same gear and same amount of life, except for the weapon, he has fury scourge and i have fury zerker axe.

I have 4 fps attack but for some reason he seems to be faster than me. How is this possible?

Does the scourge have a faster attack frame somehow ?
or is it just me having bad luck???
