I like to test leagues, bronze to diamond, like it was before in ranked in survival. They will have different cooldowns based on leagues. Lower the higher number of days. People can choose which leagues they want to be. Can can be matched with higher or lower league 25% of the time but 75% of the time they are matched within their leagues.
And I also like to try your option fir 2 weeks.
Yeah thanks, imagine we had enough resources to running a couple different modes side by side for a season or two - that would be some serious A/B testing!
I'd also be really interested to see modified versions of leagues, and different cooldowns seems like a good approach.
I can live with one after the another test, tagging @royaleagle to read this.
