@Riot, this is basically what you're doing to Azir.

Q - Now a Skillshot Q - No longer refunds mana or halves cooldown on minion kill Q - Can no longer stun
W - Can no longer stun with Pyromania
E - Can no longer charge Pyromania
R - Now has warning particles and can no longer stun.
Honestly focus on nerfing actually broken shit and stop worrying about Azir tainting your plans for LCS big plays.
