Don't pretend you know how to play Kayn...
...If you can't play both of his forms. I am getting pretty tired of seeing all these
players that ONLY pick darkin, regardless of how the situation is. While yes it's true that darkin is stronger and easier to learn, but that doesn't help if you pick it into a team that counters darkin heavily. The last game I was up against

And yet still
decided to go darkin and got his butt whooped. I didn't think that he was a worthy ban in ranked, but I might start to ban him myself so I can stop getting Kayn players that only knows how to play 1 form.
