So I wondered why yesterday on LeBlanc I only had like 1 win out of 9-10 games. I remember in each of those games I would at least 70% of the time have very glitchy instances in the game where I would Q an enemy then try to R, W them, I noticed after I had used Q, W, E that my ult was still up and it had etheral chains as the next ult casts.
For the odd times that my Q and R did cast consecutively without error, I noticed that W would 60% of the time fail to proc R's mark damage... I don't know what Riot did in this patch that made these actions go unregistered but it's pretty much a game breaker for me as a LB main seeing as I dipped from 64% winrate to like 45% yesterday... I tested this out in a bot game and I can yield the same results... Stay tuned for video evidence.
