In regards about the Casseiopeia changes from PBE changes.....
Cassiopeia Noxious Blast (Q) mana cost increased to 40/50/60/70/80 from 40/45/50/55/60 Twin Fang (E) mana cost increased to 50/60/70/80/90 from 35/45/55/65/75
....according to the latest PBE changes.
No one is even gonna use her, and you want to worsen that situation? I don't get this. I never even had a single Cass player, be it ally or enemy, in any of my games, what the hell is this nerfs for?
