PLEASE RIOT: Aery and Teemo

Aery is the 'meta' pick on Teemo right now because of it's consistent, sustained DPS; Teemo easily triggers two aery hits with two auto attacks.

HOWEVER

Teemo has no shields and misses out on half of the Rune's intended purpose Aery flies back to your location, giving away Teemo if he's stealthed and somebody steps on a mushroom; anywhere on the map

Arcane Comet is also so garbage on Teemo because only his shroom provides enough slow power to increase the chance of it hitting, it's worse than both Aery and Phase Rush because it can literally do nothing as you have no way to gauruntee a comet hit.

Teemo needs to survive the lane and have laning power in order to get a foot-hold on the map in mid-game. Phase Rush is probably the 'best' for Teemo in theory because it's useful for movement speed in an all-in or trade, and it's border-line OP against champions that rely on a slow like Nasus. In some distant universe, Arcane Comet could have been great for Teemo because going 3-points in Blinding Dart by lvl 5 is a relevant laning strategy, Q'ing people with a comet proc would be cool.

But Aery is the 'BEST' in practice because of the consistency in extra damage it brings to lane, even though it BREAKS YOUR FUCKING PASSIVE and outplay potential (Yes, Teemo has outplay potential.)

"Okay, what about the other trees?"

Sorcery has some things teemo really wants, like manaflow, move speed, and Scorch. Resolve secondary is also important if you want to survive lane. Going another Primary tree just for another keystone means sacrificing something else, and is not exactly a net-gain. Plus the other keystones in other trees are questionably useful if at all.
