In the league client. under champions there is a filter option for...tanks, supp, mages...etc Teemo is under "Marksman" Can he be moved to "mages" or have his own "Hell-spawn" filter I do not want to see Marksman Teemo in my games
cuddlykitten43 votesOh, he's a mage, not a marksman? Guess I was just thrown off by the blow dart gun that he uses for all his damage except the shrooms.
desertoflame2 votesLet me add some 
, I guess what I am trying to say is that the "Marksman" role is filled with the "adc" champions. And Teemo sticks out as one who would build ap over ad. So my logic is wrong that he isn't a mage because "marksman" is not "adc". But still I think it could be looked at a bit more
Duke Anax3 votesYou got it backwards. The ADC role is filled with the Marksman champ.
Teemo is a marksman, because he is based on ranged Auto Attacks, But simmilar to Urgot he is not well suited as an ADC.
Sukishoo1 votesMarksmen are those that rely mainly on Auto Attacks, which Teemo does.... therefore he is a Marksmen.
ActuallyArrow2 votesI love when I go Teemo top on Team Builder (and use the tag Marksman because why the hell not?) and people flame that I don't know how to play Teemo.
Sukishoo1 votesIt's cause Teemo IS a marksmen, just like Corki, Tristana...
He used to be listed as a support, which was horribly wrong.
TecToNiiC1 votesWanted to say that "satan" is not a role yet but got shen'd by op 
Tsugaga1 votesTeemo is a marksman, he just also works great as AP, like Tristana.
Duke Anax1 votesThose two have little to do with each other. So as you said, they are not exclusive.
KaisadiIIa1 votesIt depends on what you call a "marksman".
