I KNOW! I KNOW!!!! Perk 1.10!!!!!!!!
Make it cost 10 perk points to log on, 5 to bring up clipboard, 10 each for bombs, 10 for each 100 rounds of ammo, 1 for each radio transmission, ummmmmm.. let's see... what else can we perk. Gosh, you know, the more I think about it, the more I can relate to all those "Perk the ____" posts.
The fact that eventually no one could log on and play because they would have depleted all their perk points is a trivial detail. LONG LIVE THE PERK MOVEMENT!
