Wouldn't be adverse to that. Also means the team with more points captured has access to resources to be able to actually hold the point or go to in order to restock before pushing other objectives.
If not ammo crates placed in the map then it should be possible to call in an ammo cache like a vehicle paradrop.
Ammo cache could be used to replenish ammo / gadget ammo once before disappearing, extends time delay for you to call in another vehicle (as in cooldown acts like a vehicle call in) so they can't be spammed. Basically allows people to get ammo every few minutes when there is no one dropping ammo crates.
Everyone does know if they switch their ammo types then you will have more ammo. Works when in a tight spot but does no one remember how recons/snipers worked in past BF which most everyone wanted?!? That class did not have ammo. They relied on others to supply them with ammo. This is the aftermath of what people wanted.
@NazT55 I generally agree with what you are saying but there are times when no one is throwing down ammo crates, or no one is around.
I'm usually fine getting ammo from enemies, but you can't get gadget ammo from enemies.
My idea with ammo caches as a paradrop affecting vehicle cooldown is there is a penalty for using them, you can only use them every few minutes if available, and they aren't super convenient (having to go to call in menu, waiting for the ammo cache to actually drop).
This way ammo crates still make up most of the ammo supplied, ammo caches are only used sporadically when the easier option isn't available.
