I think his passive would be too toxic. How can Leblanc play against Pikachu? She might get stunned when she W's ... Or Akali, or Katarina... there are a lot of diving assasins, and this passive would wreck them hardcore with no counter except to make sure to have a BV ready to go. It would also own champs like Karthus or Ezreal, who rely on spamming poke spells.

Riot already removed dodge, which was the closest mechanic I can think to this.

I would switch it to deal damage or something, but no interrupts. Or, maybe it can charge them with static, and then one of Pikachu's abilities can activate it on contact for a stun. That would almost be like a tweak on Annie's passive, which has been doing fine for years.
