Maokai and "Spells"

Mao's passive procs on literally anything that deals spell damage. It needs to be fixed. Senna's ability makes her allies' auto attacks count as spells. Summoners attacking mao activate his passive with every auto attack. These things are not spells, they are simply magic damage. Fix the programming on him. You can go attack speed with him and this fool is healing EVERY single time he attacks. Not working properly.
