Azir Turret Damage Not Standardized

While not particularly a bug, this is probably an unintended change. With the recent changed to minion HP in patch 6.22, Riot added the following changes to turrets:

DAMAGE TO MINIONS: Turret bullets now deal a fixed percent of minion max health: MELEE ~45% health per bullet RANGED ~70% health per bullet SIEGE ~14% health per bullet SUPER ~5% health per bullet

Playing a game of Azir, I've noticed that his Disk of the Sun does not follow the damage indicated above. I'm not sure if this is intended or not, but it now takes several more shots to kill minions (at lv 6 at about 6 minutes it, it took 4 shots to kill melee minions and 3 to kill caster). If this is not intended, it should be changed to match the damage of all the other turrets in the game.
