Doubt that's what they are talking about if the mechanic was undiscovered before this year. Stick + vision mechanics have been well known for a while, I learned about it when I read about the Kunkka mid matchup. Might have been Pajkatt buying mangoes and using them out of vision last year? Not sure, my memory of the details is fuzzy.
