Let Twitch cast E while moving
Small buff that I think would help him out a lot. When you reach late game it's not always worth it to even cast contaminate when you can keep auto attacking. Twitch also tries to 1v1 enemies a lot, and if that duel is really close, that small cast time can be the difference of weather he wins or loses by procing those 6 stacks. It's really frustrating to die mid contaminate.
Q though it is alright to poke with because of its long range
first
is that you need a lane swamp to enable him to survive the lane phase. A strategy that is not arround in regular solo Q.
