Honestly, there's not a solid opinion from my end because the characters in the Global version launch have changes in their skills. I do know that there are a lot of members in the global community who want to save for future characters and get the best meta characters. But, I would say that you shouldn't make any judgment or have high expectations just because a character is completely broken in the Chinese version, but when that launches in the Global version, your hopes are shattered. A prime example is Cobalt-B, who has received changes in her kit and now has better Shatter compared to her Chinese version. For the time being, invest in characters like Nemesis, Tsubasa, or Cocoritter, who can help you in the long run and won't be power crept for a long time.
