@Riot The real cause of Malzahar's ban rate and where be should be nerfed
So new balance changes for Malzahar have dropped on the PBE, this time hitting his movement speed and AA range.
The problem is that these changes will not affect Malzahar's ban rate and the core part of his problem. In order to fix Malzahar, you need to address the elephant in the room, his passive. I would personally like to see Malzahar return to his previous passive as his Voidings felt like more of a reward for playing well, but doubt that will happen.
Instead, I recommend removing the damage reduction from his passive, for the very least in the 1 second window after his passive is triggered. This will allow Malzahar to get poked down when his shield gets triggered instead of being able to laugh it off. He will lose the safety that you intend by reducing his AA range, and it will reduce his survivability, which you intend by reducing his movement speed. Hit the core of the problem, not the side effects.
TL,DR Don't hit Malz's base stats, remove the 90% damage reduction from his passive in the 1 second grace time after it triggers, or entirely.
