The Invisible Man is displeased with some Guilds' tricks. So he has changed the rules! Listen carefully:
First of all, If the Guild has no spare rivals at the Grand Arena at the moment (аll avaliable according to the Guild's rank rivals are busy at other fights), no rival will be suggested. You'll need to wait till the fights of all potential rivals are over.
Secondary, when the fight at the Grand Arena has started, the attacking Guild's wanted place in the Rating Table is recorded. If the Guild wins, it will get this particular place, no matter what Guild is on it, when the fight is over.
Thirdly, The Invisible Man has allowed Giuld Leaders and Treasurers to change the day, when Guild gets Grand Arena's rewards once in four weeks.
