It's not a kill-steal unless someone has their name on the person first. Because each player's name shows up when they are in sight, they are the owner of themselves and therefore own the right to kill themselves. In conclusion, the only person you are taking the kill from is the person and that person is responsible for not letting anyone take his life from him. Either way it's a 3-second respawn.
arent some of the gametypes missing or are they preset gametypes that are on the game automatically (and cannot be deleted)
