Ao Kuang has been suffering since his last nerf. We've chosen to focus his Season 3 on being a stronger Late game pick, and as such have adjusted his base scaling on several stats.
Increased Health Scaling from 74 -> 82 per level.
Increased starting HP5 from 7 -> 10.
Increased HP5 Scaling from 0.48 -> 0.7 per level.
Increased Magical Protection scaling per level from 0 -> 0.9.
Increased Magical In-Hand Scaling per Level from 1.7 -> 2.4.
