Ok I'm pretty sure I'm not the only one who has thought about this. When ever heavy ammo drops in either of those game types, the player/team absolutely decimates with it. Those two game types usually come down to skill until heavy ammo drops. Once it does, even the team or player that is losing can gain a massive lead and come back to win just because they gained some heavy ammo. I guess what I'm trying to say is heavy ammo is entirely unbalanced in those two game types. It gives who ever picks it up and unfair advantage over other players/teams. It then becomes next to impossible for others to compete. Also if the person is really a scrub, they'll ration their heavy ammo out just so they can pick up more when the next drop happens.
