Kayle E Bug

Hi guys! So I've played Kayle over the last patch a couple times in both the top lane and mid lane, and I've noticed that when I take thunderlords on her it procs on her E in two hits. My line of thinking is that somehow the base damage of her auto, plus the magic damage splash hitting at the same time is what is is causing the second hit proc on thunderlords. I didn't really test it thoroughly, and maybe I should have, but I've managed to reproduce it in both games I've played with her. And I made sure the second time to see that I didn't use any other abilities prior to E. Anyways, if I see it happen again then I'll update more specifically when it happens/with who although so far it doesn't seem to matter. Hope this helps make the game we love better and more fair!
