Still cant get my head around how this bracket works :/Ok. So you're in group D, in the low seed. There are 4 different seeds (Top, High, Low and No) with 2 people in each seed. The "Top" seed has the 2 people with the highest ranks in your group. The "High" seed has the 3rd and 4th, and so on. You are in the "Low" seed, so that means out of the 8 people in your group, you are the 5th or 6th highest rank on your group.
Since you are in the "Low" seed, you will play 3 games. One with a Top seed player, one with a High seed player and one with a No seed player. This system is used for big tournaments to prevent the best teams from knocking each other out early on, which means that the final games will be much more close and exciting.
If you get in the top 5 of your Group, you will qualify for the main tournament with the 40 people who qualified through the group stage, and the 24 people who automatically qualified, making 64 people total.
(Sorry if this is a bad explanation)
