Assassins using darts after 2.3, still worthwhile?

With the poison weapon changes in 2.3, are darts still worth it for assassins and ranged-poisoners? Stacking that poison was what made darts great. I guess spreading the pain in groups is still viable, but that sure does take a lot more micro-management.

It seems that without poison-stacking the dart advantage diminishes greatly, leaving short-bows and/or throwing daggers (mainly in SoA) as preferred assassin weapons.
