I'll pick it up straight away if I want to. 2 reasons: You shouldn't be abusing heavy ammo. Most people on my team are idiots, which not even heavy ammo can cure. And if you're good enough you don't need heavy ammo. You might ask, 'well the enemies will use it, so I will use it', to which I say you should stop the enemies from getting it in the first place. Edit: Clearly many people taking this very seriously.
