ok im sure at least half the people that play this game have wondered about this. mainly i think this would affect parkour and sparring. just imagine the insane tricks you could do with a third person or the epic fights where its a free for all or even perhaps a team deathmatch

Not possible because it would cause too much lag, I believe this used to be possible, I can't remember though.

Has been suggested multiple times and has been turned down every time due to the drawbacks of implementation.

Please read the rules and search whether a suggestion has been made before you make it.

i dont see how its much different from any other multiplayer game
