what is this "BO1" argument if 0 elimination matches are Bo1s? why does that matter?
also both teams get 3 bans each and play on the non-banned map. Seems fair enough for an opening match.
Single Elim - are all big Counter-Strike tournaments invalid to you? I prefer Single Elim. That way the grand final is actually fair unlike double-elimination VCT internationals where the team that gets to the grand finals from the upper bracket gets a 2-map ban advantage (leading to an unfair grand final).
