If you create the teams before the tourney it isn’t optimal balance?

I’m going to assume you mean some RNG bot creates all the teams from a list of participants. Problem with that is that it doesn’t address any problem of “noob stomp” teams as they still exist and will come down to the whims of a pretourney draft. It also means that high rated players have no way of coming up with some sort of teamplay with their team and the games are just the same low quality garbage of just playing 6v6 dual gap in custom games that Saturday/Sunday. So why even bother having the tournament instead of joining the dozen dual gaps online at any point?

Me and Thomas played yesterday, you can check out my POV here: https://www.twitch.tv/videos/719165563

The BO7 took a little over 3:30hrs and included a 1:20hr(ingame time) Isis match with an insane conclusion. It was a fun series, the wager definitely added some intensity to the games. GGs to Thomas.
