and not a toggle like Ashe Frost shot? I dont want to delete teemo or anything im just wondering.
You want to delete Teemo, stop lying.
We all want to delete Teemo.
Because Twitch has to stay out of turret range for 6 seconds after autoattacking, so Teemo needs to share the pain, because all pain heaped on Teemo is good.
Otherwise he would be too OP with liandry's applying on the dot damage.
Because it doesn't cost any mana.
(also, why do you want to delete Teemo and not Singed is beyond me; they're basically the same champ - they press Q and run away and you die chasing them.)
Ashe's Q costs mana, so they gave her the ability to toggle it off so that you don't oom yourself by autoattacking.
Teemo's E does not cost mana, so it is not necessary to make it into a toggle.
