Cassiopeia Rework - Ya'll complain too much.
Seriously. When she had her first real rework last year from Stashu, ya'll were crying about how you hated everything about it.
She got basically pushed back to what she was before the last rework with some minor (I really don't see them as major, TBH). But now ya'll want her reverted to the state you FIRST hated so much.
