You can't seriously be considering buffing Teemo
Of all the champions in this game, regardless of their current state and Kit issues, this is literally the one champion you cannot directly buff. No phreak intended here, but figuratively and literally, he has the absolute most toxic kit in this game. His kit serves no other purpose but to frustrate you.
I get that it's PBE and nothing is ever set in stone but to even be considering this is insane, have you lost your minds? Don't even give me that bullshit about Teemo players deserve a right to not have their champion be trash tier, they know what they got into when they decided they'd main a champion like Teemo. And players who don't play him equally have the right to not be driven to the brink of insanity by playing against such a piss poor excuse of a design as this. He doesn't serve any purpose, instead of buffing him, you need to rework the fucking shit out of this champion and completely overhaul his kit.
These are also changes that are making him EVEN HARDER TO GANK, and for many champions that have the displeasure of laning against him, camping Teemo is often the only way they're allowed to have any interaction in the game. This champion can't be good, he already got a massive indirect buff with the rylais/Liandrys changes and you're considering this now. Seriously, what the hell is wrong with you people. I'd rather you fucking buff Yorick before buffing this abomination.
Please, Riot, get a clue here. This is not a good move..
