One thing 343i was worried about was about the proliferation of power weapons littering the battlefield.
Well how about this… Give us a choice of two power weapons or an extra ammo crate for your main and backup weapons (ie the ones you choose in your loadout).
I mean… come on 343i… When support troops usually drop ordnance on the field they usually include Beans, Bullets and Bandages… and the occasional power weapon.
Then you could increase the time weapons stay on the field after someone dies. At least make the weapon stay longer than the body.
