On the note of grenades, it would be nice to only be able to have your grenades restocked once while you are alive. It could help with the initial barage of grenades you experience on karkand. I only suggest this because I have seen 2 guys throwing nades and having another resupply which after a while gets to be an absurd amount of greands being thrown at the hotel, also could be considered stat padding if thats how you want to look at it.
