Reminder: Zac has almost 56% winrate...
...with playrate rising each day together with the banrate. He was fine before the rework, the only """outdated""" part of his kit was the Q.
Then for some reason you decided that you had to change more because of "tanks update" and now we have to deal with something that wasn't a problem in the first place, both in terms of winrate or playrate. He passed from garbage tier to god tier. He is basicly oneshotting people just by building full tank... considering his engage this is definitely something he shouldn't be able to do.
Please next time before touching things that are fine think it twice. Thank you.
