So,i came up with two suggestions.
1.I was on server and saw few random players got kicked because they didnt agree to rules,and they didnt came back.I suggest that a window comes up when they press "I don't agree" which says:Are you sure about this(or somethin like that)..then they have "Yes or "No.
2.Ok,so this one is short.
There should be a cmd /dr which means /duelrespawn..im sure all of u are lazy to type it..(:
