Yes I will be your asistant
About DC you are right. If your team lost in round 1 you are out of DC. If you didn´t play in 1st round you can join a team that doesn´t have enough player, if I remember correctly
You are right Alex. Priority given to players who have won in first round, then to players who have not played in first round, but if not enough people, losers of first round can join teams as well as alternate.
