First off knowing when to pull heavy is all about Map/Radar awareness. Seems how majority of Destiny players have none; here are some basic rules for heavy. 1. If you suck don't pull heavy ever. You will do nothing with it, and you always pull it at the wrong time. 2. If you suck and you hear heavy ammo in bound just run away. Go to the furthest point away from the action and stay there. Please stay there for the rest of the match. Should have been there the whole time. 3. If you suck, but not as bad as say #2 - always rush opposing teams heavy, and be a meat shield for those few legit players sniping/supering opposing teams heavy. Your cannon fodder anyway act like it. 4. If you suck and don't have heavy, but another team has heavy. Become a meat shield and take rockets; because cannon fodder. If on that rare occasion you manage to dodge one than make sure you "X box record that", and put it in your badass clips. 5. If you suck please just run strikes. Thank you
