unintentional nerf on attack speed runes / masteries or warwick?

With my full attack speed rune page, minus armor yellows WW would start level one with .97 attack speed.

I dont think anything in my masteries changed at all...

Now, it's .94

Just trying to figure out why my attack speed has dropped.

I'm a WW main with 500k champ points as him and I'm really keeping my hopes up that this new WW patch will let him be played more competively in comparison to "high skill" champs such as rengar and kha'zix who just got ridiculously powerful out of no where...

But I can still beat a rengars ass no problem :I
