I've actually been having a hard time getting more than 3 stacks off a single W. A minion wave of typical size is usually too tightly packed to get lots of stacks - body-blocking the arrows is actually a lot easier to do now on the new W and enemy champs are rarely positioned in a perfect fan formation for you. Building stacks prior to a teamfight off successive W poking alone, even with a 4 second cooldown, is still unreliable. As an ADC, especially an immobile one like Ashe, you generally want to be a good distance away from any frontline initiators. Especially while champions like Sion and Sejuani are likely to be the tanks you'll be facing down.

The big problem with TBC on Ashe is, outside of getting full Q stacks and targetting different champs with each auto attack (not the best behaviour for a teamfighting ADC), is that it is hard for her to efficiently stack Cleave on multiple targets. That and the drop in DPS while you sit on that Phage and/or Kindlegem (mostly the Kindlegem). If you have a heavy AD comp, you probably have a Zed mid, and while he is more focused on single-target burst he has enough AoE that he could probably get stacks out faster than Ashe could.

As for Nasus, he is kind of in a weird spot now that armor stacking is popular. To be honest, as the primary meat-shield Nasus probably shouldnt go too aggressive in his build with a Trinity Force. If he really desires to keep his damage relevant against enemy tanks, Gauntlet+LW is the way to go, and build full tank from there. Or maybe just not pick him as part of a heavy AD comp.
