Delete Teemo
I am not complaining that teemo is over powered or anything like that, I am saying that Teemo is a very bad champion and is there only to be annoying, that's it.
I'm a top lane main and I've played countless games against a Teemo, and every 10 games I play against a Teemo, I would win lane like 8 times out of ten. And its not because I'm a Yorick main or anything like that, Its because I know that Teemo is a poke champion, and if you try to all in him as ANY champion, you will most likely win, unless he is reallllyyyyy far ahead of you.
Unless teemo gets a HUGE lead early on, and I mean like a HUGE lead, he will be useless past the 20 mark. He doesn't have enough raw damage or range to be a backline mage or marksmen, he's not mobile enough and doesn't have enough burst to attempt to assassinate a squishy, and he's never going to tanky enough to be a frontliner.
Honestly the only thing that Teemo does well is splitpush because he can set up shrooms up in the enemy jungle to spot people trying to stop him, but honestly Teemo even loses the splitpush game to more meta top laners like Tryn or Jax.
Honestly the only thing Teemo has over other champions would be his ult. But that is easily countered by the new Red Tricket
.
Now I was over exaggerating when I said delete Teemo, he can't be deleted. At this point hes basically the mascot of league of legends, really he works better as a meme then a champion.
So heres my suggestion, give him a Sion or Gangplank level of rework. Complete re imagine his kit and give him a new character model, because to be honest his current one is ugly as hell. Make him less annoying but more viable over all.
