As you know in WotLK windfury totem gives us 16% haste and can be improved to 18/20%.
So using most popular 2.6sec main hand weapon and without haste at all with flurry and improved to 20% WFT active we'll have 2.6*0.7*0.8=1.456 attack speed and WF can proc every third hit. If we won't improve WFT it will be 2.6*0.7*0.84=1.5288 attack speed which let our WF proc every second hit. I think this can provide more DPS!
Am I right?
