Being the TO of this event I think we should have look at this between the Team Leader first before opening and "bothering" the C&A team

.
I went and look at the game log as a first part of my investigation, yeah it appears that the randomly setup group has 2 team mate into the same group therefore playing into the same game, I'm not sure any action has to be taken here since MY1101 dropped troops and take a 1 troop territory for his team mate (updalions). I don't see any abuse nor cheating in this (I didn't setup a sitting rule into this event and for all sports). The sitting action from MY1101 will not benefit his own turn neither.
Remember, this whole event is mainly based as a Large Team competition, I agree that it would be better to have a sitter that isn't part of the same game but maybe their wasn't any other choice at this time, that is maybe a rule I can insert into the event main thread that apply only for game where team mate are playing into the same group, lucky is that if a rule is establish now it won't change that above game because the sitting wasn't "malicious".
I know for sure that updalions was off this weekend, coincidently I was facing updalions in a best of 5 match part of a separate tournament (Random 1v1x8) and I played against his sitters all weekend long. I know that was 1v1 and not a Terminator multi player game but this should eliminate the "cheating" aspect of this claim.
