I'm actually excited about the next patch!
Cassiopeia looks decent, Malzahar as well, we're getting rid of Sated Devourer (even though it works great on Shyvana, I never really liked the way the scaling on it worked) and Guinsoo's is gonna be more difficult to use properly (Phantom Hit will be annoying, but the item seems more balanced, albeit weaker).
I just dread that both Malz and Cass are gonna be popular as hell after the patch, I kinda enjoyed playing them and feeling somewhat unique.
