I'm 100% confident that Skill trial Obito 10tails will be THE ninja that will end Naruto meta on the chinese servers. Ninjutsu immunity too strong of a counter. Give him scaling, increased mystery/standard damage/reset and he will be super strong. There is really no other ninja that doesn't have skill trials right now that can fight 6p Naruto or Madara in the future (every non dodge/immune ninja just can't fight 6p naruto by default) so you are sitting on a future gold mine don't worry.

There are some leaks as well that Toneri is coming for CN server so he might be the next OP but that's hard to say if he is even coming for real or not.
