Not only me, many people had used til Season 6 Zac not only Jg also top!
I was also a Top laner, who reached til D3 in S6.
After Remake of Zac, he couldn't stay more as top laner cuz of 2 huge Change of Skills Q and R.
As a result that Remake deleted Diversity of Champion!
Some Champs are being better after Remake and some Champs are not!!
As i know, already Rengar, Le blanc and Twitch? were Roll Back and Why Zac shouldn't be?
