@Riot: Champion-based poisons should not be able to kill large jungle monsters; reduce to 1 HP

Ever had a Twitch who leashed for you, but accidentally kills the Gromp with his passive poison? Or a Teemo whose Toxic Shot poison took that Blue Buff that you actually needed? ANNOYING.

Now, a lot of people would just say "Save your Smite", but some people want that Gromp Buff off the bat so it takes damage from the Poison Armor. Or need to Smite the Krug immediately for those stuns.

To that end, how's about making it so that if poison-capable Champions like Twitch, Teemo, etc., aren't carrying Smite, their poison can't actually kill large jungle monsters? Instead, it would reduce them to 1 health, much like the Machete effect, Gromp buff, or Cinderhulk can't deliver the killing blow, and instead reduce the monster to 1.

Shouldn't that be easy to do?
