Give Teemo a real role. Also Scuttle Crab hate general.

Teemo is pretty fun, but recently I've found that if he comes up against an AP mage top laner like Lissandra, Kennen, or Rumble it's hard for him to stay competitive.

This is due to his high damage over time, rather than burst damage, CC and utility that other top laners have. Also, with the addition of the scuttle crab, shrooming up the river with our new shorter life shrooms is basically impossible.

For example, playing vs Lissandra should be possible with Teemo, however blinding dart does absolutely nothing outside of the minimal damage and his main kit (movement and baiting people into mushrooms) is completely voided by a teleport and two lots of hard CC. I feel like after Teemo's damage was nerfed a little, there's no inherant danger in just going all in and spamming your spells. His main damage mitigating move is useless against people that don't use auto attacks. So why not put him in the bot lane? Well every other marksman's ultimate has a direct impact in a fight and doesn't require chance for it to be successful.

Even Gnar (who teemo should be able to go toe to toe with) is difficult as he draws most of his damage from his abilities.

I really enjoy Teemo but he doesn't feel right in top lane, he doesn't feel right in mid lane and he doesn't feel right in bottom lane.

His kit does actually lend itself to jungling but Teemo doesn't have any sustain in his kit, so he tends to get battered in there.

I really think that Teemo should be reworked as a real jungler, keep his trademark mushrooms the same but tweak his q, his w and give him a little sustain.

I suggest his q blinds everything. All spells and skillshots will miss until it wears off. It doesn't really make any sense that his q only blinds a champion throwing an auto attack, but has no affect on their ability to perfectly land a skillshot on you. To reflect the innate power in this, you should up the cooldown.

A second suggestion for his q is to have it act like Fiddle's fear, disorienting the champion for a second or two. This would fit better with Teemo's jungling kit as it's useful to have some CC to help gank lanes.

WOW SO OVERPOWERED you might say but look at yasuo's wall? Blocks all skillshots including ultimates? There's plenty of abilities designed to counter skillshots in the game.

I think that Teemo's 'e' should give him a small amount of lifesteal, like Vlad's q but not as drastic. Something to help him fight those badass jungle creeps.

tl;dr, Teemo doesn't really have a home. Lets mould him into a real jungler and have him be a terror to invade. His kit lends itself perfectly to objective control and setting up teamfights/ganks (if you add a little CC)
