I strongly request (and recommend) that the organizer prohibit swaps. A swap is when a player is replaced by another player from a different team. If a forced replacement is necessary, then a player in the team should be replaced by someone from the list of substitutes! A clear example is the previous tournament in this series, where a swap took place that significantly affected the balance of power in Vitaly's (aka Gomunculus) team. I'm not sure if they would have won if it weren't for Yegor.
