Whats with the new darius build?

{quoted}

what made people think it was viable?

Increased attack speed allows darius to stack people faster when in melee range. Little do people seem to know that darius's main form of stacking should be his Q and then W which resets his auto attack (like having 2.5 attack speed for two autos!) and then Q. That leaves whomever with 4 stacks so all you have to do is one more auto.

Trinity force provides very little tank and compared to BC guts the shit out of darius' damage since he scales more on AD as opposed to attack speed (all of his damaging abilities have an AD scale).

Let's put it this way, when I want a damage item on darius that isn't black cleaver, I get deaths dance or steraks.
