The truth, teemo is an invis champ, riot dont like buffing them.

He can stay invisible for as long as he wants and take no action without breaking invisibility, including moving. Its kinda like going afk. I have a tough time thinking that this is more powerful then any other stealth ability.

Here is a list of AP based single target "nukes" at better ratios then Teemo's
(Mages other than Zilean are missing from this list not to scue it in my favor but in general casters have entire kits that function with AP as a whole, better then Teemo)

Twitch and Eve are both being reworked in the Stealth patch coming Soon TM.

Said by someone who has never played Teemo before

How is the longest CD for an escape move in the game mobile? Highest AP Ratio, are you mad, see a few post below to see a plethora of champions that have better ap ratios. His map awareness is the only thing about him, and his invis is him going afk. That potential is for him not getting focused which goes for any carry, but guess what, they can do it faster and more efficently with other carries, please bring proper facts before complaining about a champion.

+1 MATE!

I've played Teemo pretty faithfully since level 10 and admittedly, since I play a lot more ranked, sad to say I can only pick him as a counter pick to Tryn and those likes (I can also dominate bot lane vayne), otherwise, Teemo is basically trash. It takes so much effort to play him at a mid elo level since he's so UP that it's easier to grab Ahri, Vayne, Graves...heck anyone and even if I played them like an idiot, I could still end up with a positive KDR, however with Teemo's range, his harass results in me hurting more than anything and I basically have to be on top of the minions to do anything significant it feels like.

As a male lover of the cutest champ in LoL, I demand they put him in a playable position so I can use the champ I mastered hundreds (maybe even a thousand...) of games ago to carry myself up in ranked instead of picking easy champs I can "win" with. He will always be my favorite and I'll continue to laugh as I beat players with him, but right now, it's almost not worth the super effort to be able to do that .

dam phreak.. we need you here ;_;

for the love of.. teemo the swift scout!

Teemo needs a better escape mechanic. Some thing that makes him go invisible.

Move Quick

Teemo creates several duplicates of himself and goes invisible.

Just thought of this for a escape/team fight/survival/mind game (That's a lot!) mechanism:

Poison Dart (Active): Teemo shoot a dart that make a poison cloud appear. While Teemo is in the cloud, he get super stealth which prevent him from being seeing by Wards/Oracle and let him attack and stay stealth. If he goes in the cloud and go out, he keep the super stealth for x time but lose it if he attack. Ennemy in the poison cloud take x damage and get reduced vision.

Let me explain a little: This would let Teemo actually have a lot of thing I find he lack.

1. Give him a good escape mechanic with a little mind game on it. Can be used for offensive and survival in team fights.
2. Staying in the cloud give you a better attack advantage while moving in and out give you lots of invisible mobility. As you can see I didn't combine both since I don't want a OP skill. Nothing stops you from going in the cloud, relocate during the effect and go normal stealth. Which is à little plus.
3. AoE and Skillshot STILL HIT HIM!!!! So no, this doesn't make him invincible. Yes he can go out of the cloud and keep his stealth for a little while, but he lose it if he attack, so he can actually just pop his cloud to make you think he's in it to make you waste abilities and or go in and out to dodge spells.
4. This doesn't work near towers. Like other stealth. Even super stealth can be seen by a eyeless tower.
5. Still have to see if he can only pop it under himself or at a x range near him. I vote for the x range near him to give him a little more mind game. Could make you stay stealth even when used so people are lured in the wrong way (maybe over a mush?) or pop it on someone for the damage and added effect.

That's was what I thought up while reading the main posts. I didn't read the other posts and if this idea was already given, I'm sorry. >_<

Also, I'm by no means a teemo player, but I understand he lacks some lust. Like the OP, if you think this is overpower or bad, please explain why and maybe bring something to help the idea? I didn't give cd/ratio and such for the reason I don't think I can give good ones, so please contribute if you want. I'll let Riot choose what they do if they take it.

Hope this is appreciated.~

This idea was not given yet, so thank you for bringing it, it is appreciated. It actually helps the discussion, and even if you don't play Teemo, you already understand him better then many others, you took the time to read my post, and you are actually trying to help the post out, unlike most trolls out there who post useless (and mostly false) things about him with no arguments to back it up.

I like the idea of the poison cloud, and the fact that he can use it for many things. He would still be vulnerable to aoe, but would not be so easily focused and taken out in 2 secs. Teemo really need something to be more "evasive". He IS after all the swift scout, but he got nothing in his current kit to reflect his tittle and the play style he should have.
