So, Fafnir

[Taint2]

I lost, what, .4% haste? Double Attack, I lost 3% from Atheling Mantle and 2% from Ravager's Gorget. 2% from Pole Grip too if you want to add that in there. I still got ~26% Double Attack from merits/gear still, that is still 1/4th of the time. Instead of 1/3 of the time. I still think that, over time, with Retaliation up, I will do more damage with my current gear than with my old gear.

TP overflow doesn't really increase damage though, except from the extra hit.

With decent Haste buffs the 6hit will win. Its been mathed out many times. Ukon has excellent white damage and you are forgetting the 120 delay attached to each WS.
