Azir + Fervor of Battle = OP? PLS IGNORE THERE IS NOTHING GOIN ON HERE

First of, sorry guys.

So as someone who really enjoys playing Azir it grieves to report this interaction as the bug it most likely is. As I've been experimenting with Azir the last few days I found out that sand soldiers are able to proc the fervor of battle on-hit as well as staking it up. Fervor is most likely coded as phantom hit (Sated Devour) which soldiers can proc since patch 5.17. Now this isn't a big problem in itself as Azir doesn't really synergy with any other keystone mastery (No crits, no burst, no DoT, no Tank), it's just that ALL sand soldiers proc it which usually ends up being a maximum of 240 on-hit (20% of my damage dealt, easy to spot as its physical damage). I would like to see the mastery fixed but keeping the interaction there by making it only proc once each attack.

EXTRA THING: Malzahar's voidlings (dealing physical damage) are not working with Death's Dance physicalvamp while they do work with red pot.
