Kog and Twitch DO NOT have a bad early game.
They have absolutely 0 drawback to all parts of their game. They have no weakness and scale better then every other champion in the game put together. You would think hyper scaling ADCs that disintegrate entire teams would have a weak early game....nope. I have not once in all my game ever seen a Kog or Twitch have a weak early game. That is supposed to be their one gate of power. It's a lie. No one will EVER be able to convince me they are weak early because game after game, match after match, loss after loss its always a damn kog or twitch. I have not once seen a game where they could not trade evenly or trade even better unless the players were grossly out of position.
