ok, I've been thinking on this awhile, on how to make it "harder" and also more customizable.
for the customizing end, gonna add a cvar to allow server admins to decide if the CT's skills reset on round or on map.
as for making it harder, I've decided that each time you win, the amount of ammo you receive per kill is reduced by 5. I will also make a cvar that admins can customize how much ammo given is reduced. so, if you were to hate this idea, you could set it to 0 and it would not reduce ammo given to the OMA.
