I feel that in these times it is good to remember a certain champion

Remember Kassadin back in 2014? If you played then you do; he had a 97% ban rate in ranked. Anyway, what happened with Kass is that Riot refused to admit that the issue with him was Riftwalk. They nerfed literally every other part of his kit, then finally nerfed Riftwalk. But now, no other part of his kit was any good either, so he just sucked. He was in the gutter for months.

Azir is the new Kassadin. Don't make the same mistake twice, Riot.
