Kingdom Tax (the 10 percent that the Order masters pay)
Just a thought, why not have that the 10% tax from owning the Kingdom Citadel affect everyone in an Order for the Tax.
So many Orders seem to run several accounts one to be the piggy bank soaking up the OvO winnings setup as the master in the Order than shuffled back into another spot. Perhaps set the 10% tax to anyone who has been a Master of the Order in the past week?
