I think that this will be a disadvantage to the multiple time reincarnated character as the amount of stars will somewhat tell if the characters is strong or not or if they players has played the game for a long time.
The advantage for this to the reincarnated players would be “the brag” on how strong one is when someone can see that they have a lot of stars. (Which to me personally is useless)
Whereas for the yellow stars players again when u click info u can only see their hp and gear like usual.
As a reincarnation player I just want to say that if “the star counts” is implemented it will be fair to do it for Both yellow and reincarnated characters.
