Echoing keys post for if a world cup format is decided on. With 8 slots (2 SV + SS - ADV), 16 teams should be possible. I don’t think a bo3 SV slot is needed, but 2nd SV could be bo3 if for some reason the demand is there. Pools format seemed to work the first two times it was hosted, and it seems to be the overwhelming preference after the weeks variant two years ago. We have alternated back and forth between UWL/UWTT & UWC the past few years, so it might not be a bad thing to continue that; it gives different members of the community their preference each year. As much as I’m not a personal fan of the format, the intrinsic problems in a world cup tour can make for fun moments when there’s a huge upset, but there being “upsets” in the first place isn’t great. Realistically, some teams have a much lower chance of winning the tour, or even going to playoffs, than others, which can be a massive motivation killer. Not going to harp on this too much since other people already have, and they’ve made the point better than I can. I think fewer slots (and a better grouping methodology) would help slightly with that issue, but enough to make a real difference? Not sure.
4 superteams doesn’t seem like the definitive format though, if last year was any indication. The tour might run better with 6 larger than normal teams, but then you run into the issue of picking tiers to get 2 slots while others get left out. I'll jump in here to mention I don't think ND Ubers/Ubers UU is a good fit for the tour for a similar reason- we shouldn't be cutting a lower gen/current gen slot to add them. CL is an interesting format but can feel a little stale when a series often comes down to winning the fixed slots since both teams are expected to win their own picks, but it would probably be inoffensive as an option. The "expected" result isn't necessarily always true, but on average you would expect a team to win their own picks more often than not, which seems to be both to the format's benefit and detriment. Trying a snake draft similar to SSD for a non UWC format could be another way to differentiate the tour from UPL, which I think should be the goal. UWC is polarizing, but it’s a very different tour from UPL, which is a good thing. CL would also be good in this regard with the rotating slots. Having the second team tour being UPL lite is the only thing that really needs to be avoided imo.
My order of preference would be CL >= UWC > Boosting Tour = Snake, but I think most of the options brought up so far would be a good fit for the tour
