On Dawn opinions are usually positive. On Misty? Eh not so much, support for her character, anything related to her(like shipping) and any idea of coming back have never been so low as its now. But than again huge number of her fans and those who appreciated character and value she had left this sites. So many people i knew and met haven0t come for years on here or bulbagarden(literally).
That and 10 years of absence caused many to lose any hope stopping to care all around.
Sorry i was distracted yesterday not noticing message until today.
Hmm its more sadistic pleasure than anything else lol. Because amount of May praising and Dawn, Brock, Misty(especially her)bashing and downgrading is very high. Offering all kind of character degradation.
But in general any thread named Misty or Dawn in more modern times on Serebii or Bulbagarden will provide what your searching for. Especially threads asking for former character return with answers as always being highly negative.
