User blog comment:ArbyMcSwagger/(Minor Passive Rework) Twitch, the Plague Rat/@comment-10958553-20150311054047/@comment-25399308-20150311171150

@Willbachbakal, I liked how you addressed of how thematically Twitch should deal damage. I had tried my best to not make his passive numerically complicated since Riot has been on board with the notion of "clarity" to clear things up a bit. Twitch is one of the special cases of a marksman who also has the attributes of an assassin, but since he is more recognized for being a burst ADC while having an invisibility, I think his E should be done away with as his main damage ability. Perhaps also removing the stacks when his E is used or turned back into a pseudo-Debiliating Poison active, that is another topic.

I think it is wierd for adding slows to his passive, because the passive damage it does would also have to be nerfed or his abliities would have some tweaks to adjust in an additional passive for his passive (lol?). Otherwise, adding slows to his passive would just turn it into the shadow of his old ability Debilating Poison, and we all know where that went after Twitch's abliity rework.
