Alright here is the deal. Ghostwiring has not been expressly forbidden either on coh2.org, by relic or in this tournament. As such we cannot make a ruling against it. Whilst we recognize it will be considered poor fair play it doesn't change previous gameplay. We will however bring it up for future tournaments.
This was my ruling in full. SwonVIP checked the match and noticed a 4-5 total of ghostwires.
