Twtichy Darius?
 

I am thinking of trying out a new Idea I had, A Crit, Speed darius

Inv:
Phantom dancer
Phantom dancer
Infinity edge
blood thirster
blade of occult

Good or bad idea? I don't want to go into a match and fail completely.

Have fun being instagibbed in teamfights.

Though I imagine it COULD work if you switch up Darius' playstyle to that of an assassin. Would be rather difficult, considering the lack of a good gapcloser and escape.

Tanky dps/bruisers function on the fact that their damage isn't terrible while building tanky. If you want to build a style of an ADC play an ADC and notice how fast they die when you are out of position. Well with a tanky dps/bruiser you are forced into being in the fray due to design of the character and with no defensive stats you will die before you do anything.
