yeah if you implement it, clan members will shoot each other but some new players will join and team to kill you 2v1 and at first they won't listen cz the rule itself is stupid and then you cant punish them for teaming, what you gonna jail them? Then they are back at it so next is a ban? Would you ban anyone for this?
+1 for everything except for
-the arena thing
-the smoke machine (It's fun to use and annoying for others, maybe ban using it when on car with others or turfing or just add a command where other players can turn it off
