@Riot Why are you nerfing everything on Tahm but the problem?
I mean, his W on ally got nerf, his q is clearer making it easier to dodge, bug fix on W, passive last 5 second instead of 3 hours, ult HP ratio down...
But he still deals 32% maximum health on W without ANY ap and can devourer you after stunning you for a total of 4.5 second where you can't do ANYTHING (and you tought morgana's cage was anoying).
Tone that %health damage down and those stacks should go away after the stun.
