Japan will improve i believe, they just lack a lot of experience in tactical fps. Pc games aren't very big for them there already and valorant is the first real tact fps that is very popular there.
eh their talent distribution is just a little skewed, like look at CR and it's very obvious that players like Ade or Fisker are just mechanically outclassed by the others
i think the new Zeta will be quite strong though, they picked up some very solid talents that are individually capable
