My suggestion is to have more weapon packs that are selected in "/SpawnWeapons", think that we could have more packs but with less weapons each, like each pack has between 3 - 4 weaps?
EXAMPLE:
Deagle - shotgun - Sniper rifle
Uzi - M4 - Granade
Sawn off - tec - 9mm
This way there would be more variety and if players want other weapons they would have to buy them at ammunations or vending machines.
Please let me know about your thoughts around this suggestion.
