Kayn's Suggestion
After a few game of facing kayn as a normal game only player, I feel like Darkin is much more stronger than Shadow Assasin do, I know that you guys have said that you guys will not giving balance change, but I do wanna say in all the game I've dont against or with a Kayn, Darkin is always the most winrate one, yes, I've seen many good Shadow Assasin players, but Darkin just seems to be more of that scary kind of a role, with those sustain make him nearly unkillable, when Shadow Assasin do have to face the risk of getting one shot, because Shadow Assasin have no regeneration and is over all squishy. I know you guys have said Shadow Assasin needs time to play well, but I just don't think that people will like to spend time on a form that is not nearly as good and try to master it. I do feel like Kayn need a change, either a buff on Shadow Assasin or a nerf on Darkin to make them equaly strong. Since right now that extra bit of damage doesn't seems to be able to cover the lost of crazy sustain and the percentage damage on tank.
Yes that is all I wanna say, hope you guys will look more into this champion and aware of some issue that he have currently. Have a good day guys at Riot :)
