Kennen broken, at least vs azir

I play kennen alot, dont get me wrong hes not the BEST but hes not bad, hes fun and strong. but for some reason the last game i played with him Azir at lvl 1 (thats a one, not eleven) did about 50-60% damage with a SINGLE AA from his minion. last week ive had NO problems with kennen but now? everyone seems to be dealing WAY to much damage, and i keep getting "unknown" as a source of damage from the damage recap. not to mention champions damage in the damage recap are stacking half the time not even letting me see what happend. riot please look into this.
