Since the new adjustment added in cooldown for these jets, I think it would be a little appreciative of a mini gauge somewhere that tells us when it is full again. May be on their back or something? sneaky assassin buff Edit: WAHHHHHHHHHH I'm sorry, my search skills failed me.
I hope that whatever they do, they make it easy to tell -exactly- how much is left. Not just a vague glow or full/not-full
