Ahh, the infamous team....er...C DQing. Receiving a yellow in the qualifyers, and a red in the elims. Yellow cards SHOULD carry over in this case to the elims. Because of in more minor or unsure of intention offenses, such as the arm situation with team C, it grants them, "a free hit" during the elims otherwise. In this specific case, there were other ways for Team C to prevent the opposing robot from haning, other than the manner they did, which would not grant a DQing, or even a yellow card.
My only problem with the yellow card, is that it forces the ref into the red card call the second time, even if the action wouldnt normally be a DQ. If it occurs a second time, and the second time it could very well be an accident, or it is far less severe of an infringment, if you dont call it it looks like favoritism or not being strong enough to DQ. Either way it can upset teams, and decrease the level of fair play. But if you do call it, your making an alliance that doesnt necisarrily deserve to lose, lose. Id go with a similar system, of warning them in private. That way, if a lesser case occurs, the only team that knows about it, is the infracting team.
