So if you are in a 1 or 2 grenade situation and you toss your base grenade, are you then left with 1 or 2 stackables and no way to use them? I guess my thought being that not everything is a 3 grenade solution, and at some point are you carrying something that is offensively worthless because it doesn't have a detonation device, but still potentially dangerous if it takes a hit from enemy fire? Or equally as important, more worthless weight to carry around?
