My thoughts on Zac
Well he has the lowest winrate at 35-37% at top jg and supp. I played him a couple of times and was a complete burden on my team because i didnt know how to play him properly. I think most of the low win rate is people re-learning him and trying to get the hang of his abilities as his new ones have never really existed in the game in a similar form. I honestly don't know thought that's just my opinion on why his win rate is so low right now.
