"H2k look like they have a good comp"

Well its pretty fair since H2K had Mundo, who hadn't lost a single game he was picked in that tournament before that game. Ever counterpointed H2K's Mundo with Vayne the tank buster who also built BoTK and LW with grievous wounds. They also kept the Vayne alive in team fights despite dives from Kassadin and the rest of the team that was boosted by Sivir's ult. Ever won that game fair and square.

just because Ever did not pick a low-dps carry into Mundo so they could complain about how immortal that guy is? H2K could easily have won the first game if they had gone for vayne instead of lucian, but as is - Ever is just ahead of them in pick&bans and deserved the victory.
