The great thing about it is that you can determine what skin you will see in the arena. If a guy likes to use all the darkest colored 109 and 190 he can to hide himself, you can counter that by deleting all the dark skins and make the default a brighter color.
This way when you see one that is not in your skins folder it will default to whatever you set the default as.....get it?
works on tanks too.
... For a wounded man shall say to his assailant ... "If I live, I will kill you. If I die, you are forgiven"... such is the rule of honor.
