Sadly, under the current set up, dojos that were pledged to Lady Tsin may not switch their allegiance - strange but true - we got to make it a little better for the newer rules - my suggestion is this - a person who wants to switch teachers may do so, but must prior to doing so, drop their dojo style and win a fight without it - as soon as they win that next fight, moving from say yellow 1 to yellow 2 sans dojo they may join another dojo. You may not switch dojos by winning a fight if you did not declare you were switching before the fight started and swore off allegiance to your old dojo. In other words you have to burn your bridges.
