[IDEA] Heavy team-boosting minigun

+Builds boost based on number of seconds fired

+Each second of boost raises nearby teammates' damage by 5% while firing

+Maintain boost by keeping the gun spun up

-Boost resets when user stops firing

-Cannot collect ammo from dispensers

Spinning the gun lets you hold your boost, but it only helps your teammates while you're actually shooting. Heavies can now support the team as opposed to blocking the view down a hallways and stealing Medics' health packs. MVM upgrades could increase the boost radius and let you pick up money to refill ammo.
