Aatrox Passive reaction with Guardian Angel

I have recently had difficulty with the updated Aatrox because of the way his Bloodwell fills, Aatrox was the first 6300 IP champion I purchased and it was a weird transition with the rework.I was recently testing a build in the practice tool and I wanted to see which would pop first, Guardian Angel or Aatrox passive seeing as they are the same thing, Guardian Angel is activated first which is very counter productive to his kit. Hellbent fades after leaving combat, which Guardian Angel removes you from combat for 4 seconds, completely removing hellbent, whereas if his kit properly was used first then, hellbent would be used, he would revive with the Hellbent bonuses, then possibly die again giving you three life Aatrox. Please take this into consideration and fix the priority between the Passive and the Guardian Angel.
