its not the lineup or roles or even confidence, its that neither Miniboo or Wo0t are a good Jett player, there is a reason that Heretics best maps throughout the year were not jett maps, and even maps that jett is good on that they would play often like icebox or breeze they would play neon and yoru more than jett, the only map they consistently use jett on is Abyss and their winrate shows why they tend to avoid using jett.
