The second warlock grenade is not dependent on the super. It's in a tree if it's own, where the options are stopping. Midair while flying, dual grenades at all time(except waiting on cool down time for both grenades) (which can be fixed by using melee cool down grenade) and the first one which I can't remember off the top of my head. I'm not debating your op just huge statement above saying your 2nd grenade is super dependent, cuz it is not.
