Kennen is everything the old twisted fate was x2.
-impossible to lane versus in a 1v1 situation if the kennen is a competent player. Shurikens deal far too much damage and counter harassing is nullified by nonstop harassment and stun.
-A huge aoe stun that does stupid amounts of damage and ensures a kill at level 6, every time.
- Impossible to stop from snowballing, and then impossible to 1v1 if hes anything more than 1 level higher than you
- Does a burst aoe for over 60% of most champions hit points which is not dodge-able without summoner spells.
- Impossible to run away from
Its really plain rediculous. He is beyond S-tier in so many ways, and in the hands a competent player literally breaks the game. No hero stands a chance versus kennen in the laning phase, and if they want to get xp they will probably have to give up first blood, essentially losing the game bc massive snowball via mejai's soulstealer.
