This is not the right way to work on kogmaw.

1. He wasnt very good, AS passive on Q, so had to choose what to max
2. As passive moved to W making his Q nearly worthless, making him pretty strong
3. Nerf BASE ATTACK SPEED

Inb4 sejuani style nerf incoming.

There are ways to make kog better. That is not one of them. Ive made a post about kogmaw earlier, don't want to copy pasta here but it has solutions.
