On pro level match taking objective faster ( like turrets ) it's the key to victory ... The utility nerfs on Azir W removed one of his huge strength in lane.
His utility got litterally gutted patch after patch ...... in his current state you need to be very skilled with him to have a good match.
Honestly when i think about Azir i think at someone who can manage the fight with his positioning and CC ( more like a Lissandra ).... now he is just a safe trader that can burst down ppl with W>Q>AA>ThLord...
Temetically whise RIOT failed just cause didn't want to hit Azir huge DMG ( jeah, his dmg it's still huge imo at any lvl ) and synergy with ThLord and Ryal
LSS: The point it's always that .... Azir's soldier need to proc spell effect? Can't RIOT just remove it ( or reduce further the minions effect ) with some compensation in his utility and dmg kit?
