We've seen this time and time again. Ekko, Yi, Yasuo; now this? Fun stuff having a ranged literal perma slow coming from a 3.5k hp teemo who rushed mallet and guinsoos into a fucking warmogs. Riveting gameplay.
because tank teemo gets shreked on by mages, extended fights and general team play, hes completely item dependent.
Same reason AP Varus exists to literally assassinate even the tankiest of tanks.
There is no guidelines on how you build something, if something is broken to the point it is detrimental to gameplay Riot might change scaling but really you are totally flexible on what you build. As CrestKnight already stated he has a LOT of counterplay.
Huh, now that you mention it I think I need to try Cleaverspam Teemo...
