Two problems, Me/A or A/Me wouldn't have flurry. And this 'fastest' attack speed is only due to double strikes.... you'd have t invest in dagger master just for double strikes. So no, I don't see IW being much good with daggers.
well, apparently with 15 dagger mastery, there is a double strike chance of 30%. This makes the attack speed around 1.00. But that takes putting points into daggermastery, and isnt the point of IW to not have points in the weapon attribute?
They attack at the same rate as a sword or axe, unless you pump points into Dagger Mastery. And even with really high Dagger Mastery, Flurry ends up being a bit faster. And you get an offhand with a sword or axe.
