Its definitely not a mod controller wise, Even with a cronusmax / titan one adapter. The gamepacks only allow for rapid fire but all that would do is make your gun fully automatic, but fire rate caps still apply. The only way to bypass the fire rate cap is with a jitter mod but currently the grenade / reload glitch seems to only be effective only with a semi auto in CoD. As of now there is no jitter for destiny so how that fire rate was achieved blows my mind.
