Attack Speed Darius is good? (Strange Darius build) :o

+ regular tanky items probably

and whatever I find to be really comfortable. Once you hit 1.0 attack speed its really easy to get 5 stacks in a single pull, all your damage goes through the roof and having it very early on gives you that threatening feeling while laning even against ranged.
In team fights I used to hang back and wait but now I flank to get that quick 5 stack and spread the ebola with Q then everyones freaking out. I'm fiddling with what I should get as the optimal way to stick to targets, takes me a whole game to test each one out so it'll take a while.
I'm saving up to finish buying the rest of my runes for attack speed, the major weakness is darius is quite squishy till you get deadmans and warmog, 1v1's are generally in my favor but you can't consecutively duel till you get your tank stuff, but when you do you can 2v1 comfortably depending on how much CC they bring.
Anyone else got some strange Darius builds?
