For LOUD to win this, they have to change the lotus comp. Because if they ban split SEN will pick lotus which is an insta win against no senti. LOUD could still win while losing first map, but it would be a big gamble on the decider by LOUD.
I mean SEN will ban Ascent or Breeze. Loud will pick Icebox or the non banned map Ascent/Breeze. This gives them probably at least one map win.
