by my understanding, this should be considered an exploit as it grants an advantage to the player which doesn't seem to be intended by the game design. but, even after this being on the main stream there was no pauses. so now, i'm confused about what is really an exploit. and rito doesn't make it any easier to understand.
so what i wanna know is: "in your opinion, what''s an exploit?"

ask VK

Its when my cock enters your mouth 🥵🥵🥵🥵🥵(but ur not wrong)

well yeah but riot is shit and inconsistent with their rulings so it doesnt really matter, their staff are all bronze 2 with no knowledge on the game

ok...even if u give this map to guild...M3C wins next map
ez

Yes it is an exploit.
