Hi Slayer4041, thanks for your suggestion.
TK on would make it impossible to keep order in this server. There would be complete chaos with teamkills everywhere, especially in the maps with the CAR grenade launcher.. because not only would the so called 'noobers' kill themselves, they would also kill their teammates. And actually killing teammates isn't even the main problem, since people would also be able to troll others by just damanging them for 90% but not killing them...
I'm not sure if the TK settings also affects verhicles, but if it does, imagine what happends if someone wants a pickup.. in the HELLO server it's normal to shoot a verhicle if it flies away without you... verhicles would get more damange from teammates then from others. And people with RPG's get mad when they can't get jet, and they would shoot the jets..
And I don't even think this will solve half of your problem, since people don't just use m79 to shoot at their feet, they are also used as longer range weapons (like at 10m distance, it's very easy to hit someone with an m79).
Also imagine this setting in the tunnels, where people spam grenades, booby traps, and grenades everywhere, also into their teammates. It would be impossible to go into the tunnels without getting teamkills, the forums would be flooded with teamkill complaints and tunnel maps would be ruined.
Finally, I have to say that if the people who use m79 are so 'noob', meaning 'bad at the game/ a beginner', why do they even bother you? I'm sure if their bad at the game they should be easy to kill and therefore no problem to you. But that's just my opinion. To be really good at an m79 requires just as much training as to be good with an AK47.. I have seen people shoot extremely accurately with an m79 at long range. By the way, the AK47 is extremely overpowered in this game, with an extremely long range and high accuracy. Perhaps the people using an AK should be called noob then?
