Having guaranteed Power ammo drops from majors (yellow bars) is great, but Kinetic and Energy feel like there's a constant Juggler modifier on. Energy and Power slots feel like they should be treated as special-use, as a way to break shields and do massive damage quickly, while Kinetics should be a slot that you should always be able to use. For that reason, it doesn't make sense to me that you'd be forced to use your elemental weapons, in scenarios that would better fit Kinetics, just so you can get ammo. My suggestion: Get rid of the ammo reserve for Kinetic weapons. You reload, magazine is full. Red health enemies have a chance to drop Energy ammo. Killing them with a Kinetic weapon has an increased chance to drop Energy ammo. Power ammo continues to drop like it does currently.
