they only need navi to beat koi right
assuming KC lose to liquid
if KOI win 2-0, then it's KOI 3rd, NAVI 4th, KC 5th
if KOI win 2-1, them it's NAVI 3rd, KC 4th, KOI 5th
karmine basically clinched playoffs unless something very unlikely happens.
If they want to get to 3rd seed though, this is what needs to happen: navi beat koi + fnatic beat liquid + kc beat liquid.
