not all active (good) raters have skill.

Paul, i'd love the new system, punish the rambo's / xp-whores ! :-)

Maybe you can make something like

*begin* - *max xp count of 4(just a random) medic / ammo packs for like 30(just a random number) sec* - after that it will count again, for again max 4(just a random number) packs. ONLY for dropping packs, revive, or fixing things is not whoring imho, its just your job depends of what your class is. But the other side is maybe that ppl only give max 4 (just a random number) packs.. but 4 packs is alot health + ammo i think ?
