Increase the timer on the supply in the middle and increase the chances of dropping naturally. This will hopefully be a good compromise as opposed to nerfing heavy weapons (cough cough Sleeper).
Bungie: puts sleeper in Special slot
I get what you are trying to do, but it will just shift the meta. Snipers and Telesto would just take the Sleepers place.
this is a horrible idea. I got a better one, play the game and stop complaining. If you won congrats if you lost get better. Stop asking bungie to clear the path for you. Losers always want to change the rules cause they can't compete.
