LCK Standing were set -pretty much- in stone 2 weeks before this. Teams don't play hard if they don't have to. Don't show strategies if they don't have to. It was just technically an exhibition match and GE got caught not caring.
The way the LCK playoffs work. GE is guaranteed to be in the Finals. (Gauntlet system Team Team 4 play Team 3. Winner plays Team 2. Winner plays GE).
So Jin Air plays CJ. Winner plays SKT. Winner plays GE.
This style rewards a team for their play the entire split/season.
Because of this once the standings were fixed, most teams didn't care what happened.
We cannot gauge anything from the games that have happened in LCK/LPL in the last two weeks sadly, because there is no impact.
