although this should be the case, there are still people who play the beta just to beat other players...and not follow the instructions given to them by the people running the beta....it is these people that ruin the beta for the other players who do try to properly test the game. It is these people who abuse the testing and as such push the dev team to make beta testing closed for as lon as possible
