I have come to the conclusion on what teemo is and why he is a bad champion
Teemo only has two effective strategies when you throw away all the cheesy ones.
Role 1-A top lane kite marksman who rushes nashors and hurricanes with a liandrys torment so he can poison the entire enemy team in team fights while kiteing, he is a marksman who applies solid multi target damage. However...
-His auto range is super small to the point he is basically always in mellee range, while being one of the squishiest champions in the game, he will quickly get blown up the moment someone notices him
Role 2- A high burst stealth flanking assassin who builds MR shred to flank onto the carry and try to kill them as fast as possible while useing his speed boost to get out
Flaw-He lacks the burst and mobility to do this effectively, so if he fails to burst, he will get bursted
Riot needs to pick which role they like most on him and rework his toolkit to do more said role effectively
