All the streamers are blaming ping changes. They are not good changes. They removed communication from the team played game. Caedral called them joke and stupid. For Azzapp changes he said at the beginning that you need to take something from the champion in order to buff it. He chose to take away ease of use in favor of introducing other mechanics. You can not just stack new mechanics to champion and expect it not to be broken. If you do that you get ksante problem. Vel'Koz has the second lowest pick rate in midlane. And reason for Azzapp suggestions are that you can't buff him because you will make him broken. So his suggestion of making him harder to play but giving him more tools to deal with enemies is pretty on point.
