Balance Temmo Please hes so over powered

Teemo is a very strong champ in the league and i think he needs a few Nerf to fall in line of being fair, His Shrooms need a huge Nerf, Their base damage is to high being 450 at max rank this is a quarter of someones health, not including the AP scaling of 50% it just makes them to strong without oracle in the game anymore u cant fight this.
Second his blind yes it is a blinding dart so it should blind for a good amount of time but its ridiculous how long i lasts, 2.5 second at max rank that's just to much where as Quinn's blind is a skill shot and only gets a blind time of 1.5 seconds. Temmo can basically remove an ADC like Lucian or Kog'maw from an entire team fight with one blind. I don't understand why the blind time is so long it should be shorter considering its a lock on ability and not a skill shot. The AP scalling on it is 80% making him able to half health you with one shot. Considering the base damage is 260. Third his ability to poke in lane is so high i think his attack range should be lowered to 480 because 500 is just to high he can bully out laners like Riven and Jax. The ability he has hes just two well rounded as a champion he has range he has poke he has dot effects its just all to much and it makes him two strong. Lastly his E i think that it is a well rounded ability except for the AP scaling 70% off your AP lets say a Teemo has 1000 AP 1 auto attack will dead 1170 damage in 4 seconds (Not including the auto attack damage or any items like ). For my conclusion i think Teemo is out of line and is two strong of a champion i mean a Teemo with 1000 AP will do 950 damage with 1 shroom, 870 damage with 1 auto attack, 1060 damage with 1 Q These damage ratios are To high and he need a proper nerf.
