just my opinion on the format but i'm not a fan of having another big 5-6 day ro256 tournament to determine who makes it into challengers (especially since it's only to determine 2 more teams and as a last chance qualifier)
instead i think a quarterfinals system would've been better and just allow the teams that placed (tied for) 3rd-5th from the open qualifiers to play:
3rd: The Nation / The Silk Road
4th: OREsports / Rat Attack
5th: Happy2bHere / The Ganaccis / Nearest Airport / NSIC
these teams were the next closest to qualifying and are the most deserving of being part of a "last chance qualifier"
