Flood mode Weapons on map no show

I dont understand why it isent like infection in every other halo game there is no option so you can make it that weapons will spawn on map unless you use drop pods
-_- lets say you want to make a map were players start with magnums and have to go find guns but the guns do not respawn to make it Real well you can not do that you are only able to make 32 drop pods but this takes out the ability to put guns up against objects and hid guns and make things look nice more less making it so loadouts are the only way to go i think 343 should make it the way it use to be were if you place weapons on a map they will appear on flood mode!
