Well this is a bit incorrect, you are guaranteed to get atleast 1 point from this. If either Liquid or Team Spirit lose on their next game, they will be going to the lower bracket so there is still chances for the team to get to the grand final through lower bracket . Well kinda unexpected to actually know someone will pick Team Spirit though
Man I hate this upper and lower bracket system in DOTA. It's hard (maybe even impossible) to predict who will face who in the quarter or semi final games. It's much easier in football where you have two sides of a draw and no team can change sides and meet before the final. Maybe I'm just not used to this system and that's the reason why it's so hard for me to predict. I usually just rely on luck with DOTA questions...
Just remember how many times it happened to Croatia to be best in the group or best in two groups and then to drop out in first game where there is no allowance to slip up in sports like water polo and Handball. While teams that slipped up before passed on. This way that group perfection gets awarded with upper bracket and one slip up is never enough to get you eliminated. This system rewards quality a bit more than chance and that is why GG is such a good pick in DOTA, they finish the tournaments strong even though they look mediocre in early stages.
