I think having a 7-year contract is too long, it should have been 5 years max. There's really no guarantee that, say, Germany, Serbia, Thailand, Korea, Turkey will be relevant enough over such a long period.
And I hope there will be at least come clear criteria for choosing the four teams for one year.
But the list for the next season looks really good. I thought it would be much worse, with some completely random teams. All of the chosen teams can actually contribute something and that's good to see.
I wonder if they'll copy the men's format completely, with 15 games for each team and every participating country hosting a tournament. It would be a bit too drawn out, but probably better than current randomness.
