I really don't understand why people say blue Kayn is weak.
Can someone explain it to me?
Just finished getting rank 7 Kayn my last game, and I have 50+ games on him, so I know how both forms work... and while Red is a god at sustained fighting and chunking tanks/bruisers, blue can just pop out of the wall, literally delete your carry, and disappear again within a couple seconds (assuming you land your W).
The forms have different strengths, but I wouldn't say either one is bad.
