Using Army of One lets -your super charge your grenade -your grenade charge itself & your super -your Melee charge your super & grenade -your gun charge your Melee & Grenade

I though about it, but Army of One gives you more Grenade and Melee energy, which in turn get you more Super energy. You could just skip the whole shebang and go straight for super, but I think Melee and Grenade is a better investment. And Army of One can be obtained on many gun types, for those people who don't like Pulse Rifles (aka me)
