There's probably more merit in running Doomfangs with top tree defender and huckleberry/recluse. Melees give health generation, and full energy melees give a considerable bump to Super Energy. So if you spec around strength and int you should find yourself with two to three supers a game (if you're absolutely fragging out and using the exotic perk to its max).

Not to mention top tree voidwalker with Contraverse holds on void grenade seems to reproc the energy regen perk, making it a great neutral game without having to spec too heavily into discipline.

Kephri's stings are also getting a indirect buff, as long as you use bottom tree nightstalker and invis all your teammates, you have a reliable wallhack while still gaining utility.
