Well to be fair, LGD also steamrolled everyone, and generally not with passive play. They only dropped 2 games total until the grand finals(one in group, one in main stage). TeamSpirit is the underdog and they had a much longer path there so obviously you want to root for them more and they're showing some excelent stuff, those Magnus plays are disgustingly good but yeah LGD didn't get to the finals with pure luck, they've been basically the #1 favorite to win and they didn't choke the whole tournament, they're just being outclassed so far. Also why I wouldn't count them out until Spirit secures that win, cause LGD is definitely the kind of team who can reverse sweep and make it look like the first 2 games didn't even phase them.
Magnus PA though... that's the kind of draft that can win against anything if the RNG gods are on your side, so looking good for the 3-0. Ah Tinker though, might not go so good if they don't EMP him.
