Reckon there should be a limit to the amount of grenade launcher refill per person to prevent spamming of grenades. Grenade spammers basically ruining the game as it becomes a little absurd having someone just spamming grenades to near spawn locations the entire round.
AIt is a little absurd to only give them 2 grenades to me. A load bearing vest for them holds over 10... you could fit 4 of them in Blue jeans pockets... though this would be a bad idea in general. (1 in each pocket mind you unless you happen to be Andre the Giant)
