The best factor SA kayn brings in the jg assassin roster.

I have been playing kayn a lot since he was released, and what I believe is the best part he brings to the entire game, is that he is an assassin that can powerfarm easily. Although they have early power, Khazix, rengar, elise are very poor in these areas with low aoe, and since lethality is buffed so the penetration scales with your level, I believe SA Kayn really has the system in his favor.

Also, them bugfixes and buffs were huge. Makes it a legit pick
