I am glad Celestalon is gone.
While class design is obviously a responsibility of more than one guy, Celestalon has nearly nothing good to show for his time being on that team. The design was overall pretty bad and it was frequently getting worse, not better. His net total contribution seems to be either zero or even negative, that's terrible. And he was very, very, very arrogant.
Celestalon is more or less like Holinka, just in another area. Yeah, yeah, you can't pin it all onto one man, bla bla bla, whatever. But that one man was making it worse, not better, he was (a big) part of the problem. So, begone, no tears shed. You can ruin HS now.
