Tumbles the Trolldragon broke the rules and played for two teams. Seems nobody told him that the two cavalry 1v1s he was invited to were part of the same tournament. He is now banned from the rest of this season. We were also going to remove all of his positive influence from the matches he played, but it seems he didn't have any, so we're going to make him do penance by reffing instead.
EDIT: For anyone interested in this sort of thing, these are the top 20 in kills going into the final week:
Keep in mind that the Mounted Infantry and the Nr5 have played one less match than everybody else.
