Brainstorming Teemo Changes

Alright, here's the pitch, tell me what you like and don't like:

(E) Toxic Shot - Toxic Shot now stacks up to 2 times. One stack of poison deals halved damage, two stacks do the same damage over time as before. The non-DoT on-hit damage is unchanged. Basic attacks and Blinding Dart now apply one stack of poison.

[New] Active: Teemo throws a smoking mushroom that explodes shortly after landing. It's similar to (R) Noxious Trap, with some key differences:

• As stated, this mushroom explodes shortly after it lands. It can't be used as a trap and it has no health.

• This mushroom simply applies 1 stack of Toxic Shot to all enemies hit, dealing less damage over time.

• Enemies hit are slowed for the duration, but it's not nearly as strong as R's slow. Something like 20% decaying over 4 seconds.

• This has its own mana cost and cooldown independent of R. Probably something around 50 mana and 15s cooldown.

• The AoE explosion radius is 400 (Noxious Trap range is 450 for comparison).

• I'm thinking the throw radius should be 650? The range for R is 400/650/900 but 400 seems too short for an offensive ability and 900 seems a bit much.

If these combined changes are a net nerf, then additionally Blinding Dart's mana cost would be lowered by 10 at all ranks (70-90 -> 60-80). Or maybe Teemo could get +25 attack range. If it's a net buff, then nerf the new active function of Toxic Shot. Longer cooldown, less range, remove the slow, whatever.
