I know it's a very weird thing to say and I'm probably just glazing. But I think Japan has too many good duelists in tier 2 while there's only 2 spots for duelists in Tier 1.
This Split we have seen players like Satoshi , Yowamu, Minty and Yuuta,Hals and absol(both of them are last split but you know what I'm talking about) . While Dep and Meiy isn't going anywhere. I think at some point, the players I mentioned will change roles which will affect their performance.
Tbh this might be too early to say since it's just advanced stage 💀💀
