So why wasn't Loulex subbed out?

In game 1, he played like crap and destroyed his team's chances to win fights. In game 2, his Gragas ults either completely missed to peel his H2K or helped the enemy peel instead of sending them back. Why wasn't he subbed out for game 3? Sure, he did okay in game 3, but I feel like a change in jungler could have seriously helped H2K more than just keeping Loulex in. If they had subbed him out, they could have been 3-0'd, but it was more likely that Loulex would let a 3-0 happen with how he was playing in the beginning of the series.

Also, YamatoCannon has an amazing voice.
