Aatrox Sated devourer glitch

This is an easily reproduced bug, and im honestly suprised it hasnt been fixed yet. When in game, wether its TT or Rift, Aatrox and the new Sated Devourer have some pretty interesting interactions. Basically what it comes down to is timing, depending on what stack you were on when either A) you got sated devourer, or B) you last died, sated and w do things they obviously shouldnt. First off, if you get a sated on the second stack, it COMPLETELY nullifies w, as the proc wont work with the double stack, so you just end up not having a w (i recently have a perfect 9/0 ranked game with aatrox where this happened, i felt so underrwhelming, it sucked.) or, if you do it on the 1st or third stacks, instead of not having a w, you have one every other basic attack. this might actually be whats supposed to happen, but it feels too strong when i have it. either way i know its not supposed to nullify the effect, so please help! (its so weird to watch aatrox attack without his passive btw, solo'd dragon with him just slashing sideways , it was funny).
