I think a big reason that optic lost to guild was the map pool. Icebox and split are the two most difficult maps to lurk on, which meant that marved had less impact. also warming up + off day for yay yadda yadda
because on icebox kitchen can be covered by an alarmbot and it can be very difficult to get good timing through mid. If someone peeks boiler you're basically dead. And on split mid is also a lot harder to lurk through. Compared to maps like ascent an haven where you can manipulate rotations more easily and there are more gaps
