If I may play devil's advocate for a second here, sometimes when I run support it can be a little overwhelming with all the people who need ammo. If I'm in a huge firefight, I want to suppress the enemy, not spending the entire time throwing down ammo and not even giving myself time to shoot. It's a little annoying because pretty much everyone doesn't have full ammo so there are ammo boxes over a ton of people's heads. That said, situations like the one in the video OP posted where someone runs up to a support player and spams the need ammo command are ridiculous. To me, the LMGs aren't good enough to justify the support class unless you're also relying on resupply points, so there's no reason [i]not[/i] to throw some ammo for a teammate. One reasond I like to play support is that so few people do, and therefore you aren't competing with teammates to see whose ammo gets picked up to get points.
