Nice work on putting this together. I think the top priority is finding ways to keep survival mode alive. I think the potential is great and a good portion of the work has already been done.
A few thoughts:
Should we change 3 months (~6 seasons) to 6 seasons (~ 3 months)? We don’t want to end in the middle of a season.
Have we considered creating Wild Survival and Modern Survival (no bots)? Then we just have leagues within those (similar to your bracket idea). We already have the code for leagues so maybe the dev lift would be lighter than implementing brackets? And since this is a trial it might allow us to hone in on potential changes to leagues for the other modes.
I would like to see more in terms of rewards for survival (not SPS). I don’t know if the right answer is glint (maybe if the glint store had more frequent updates), survival mode reward cards, survival mode titles, daily chests, etc… things to make the mode more fun and engaging.
