Excellent point. With hardline pro someone could just huck a grenade in somewhere they know a lot of people are fighting, i.e. the pipe in Hardhat, the stair room in Bootleg, the circle room in Dome, etc, then run away, get probably one kill from the grenade assists, kill someone somewhere else, resupply grenades, rinse and repeat, would be way too easy to get kill streaks
As much as an avid stinger user I am, I don't think resupplying it would be smart, at least not every time, maybe a percent chance or something.
If the enemy has ~3 players doing UAV with hardline, there is so much stuff to get in the air, with resupplying you would need 2 shot down, one player killed and resupplied from, then another shot down to get a pred...
Not to mention that it isn't hard to get 3 points with a stinger if the enemy calls in a Strafe Run
