PAIN. TRAIN. SINGED.
Ok Riot. I've been patient. I've been hopeful. I've been waiting for you to figure this one out yourself.
But no longer.
Introducing: PAIN TRAIN SINGED!!
CHOO CHOO MOTHERFUCKER!!
His gas from the bottle now is black smoke and comes from a train smokestack. His shield is replaced with a cow-catcher. His sticky splat is replaced with an oil slick.
AND BEST OF ALL, HIS ULT MAKES CHOO CHOO NOISES.
C'mon guys it's all right there. Make it happen. Please.
