We have teams celebrating their draw because the competition is not even. Is 100T a worse team for not being able to get out of a group that had 2 semifinalists than the current quarter finalists?
Is whoever wins GenG vs EDG better than loser of DWG vs T1?
Playing the bracket from GenGs side, it is actually much easier for GenG to win worlds than for them to win LCK
Here's what's interesting though: This isn't the fault of Worlds seeding or of the quarterfinal bracket. This is the fault of regional seeding. The fault (in my estimation) lies with the LCK. Gen.G is LCK #2 and T1 is LCK #3. By all rights, the way that teams were seeded, 100 Thieves are supposed to have an "easy" Korean opponent when they draw LCK 3. The reason C9 and Rogue were in the group of death is because they faced actual top teams: LPL #2 and LCK #1. Such is your life when you're LEC #3 and LCS #3. That's rightly deserved.
I think it is very, very reasonable to assume that EDG as LPL #1 should be seeded higher than LCK #2 or #3 and to consider them favorites. The bracket only looks stupid when LCK #2 is actually weaker than LCK #3. Both topped their groups (one more easily than the other, don't get me wrong) but those teams should still have been switched. Gen.G should have been in the EDG 100 Thieves group and T1 should have been in the MAD Lions TL one. Those both seem like incredibly reasonable groups, fairly seeded. But they weren't drawn because the LCK took their second best team and gave them the third seed. Why? Because Gen.G beat T1 in the spring playoffs and lost to T1 in the summer playoffs. That was enough for auto-qualification as LCK 2. Gen.G won a single bo5 in the spring split.
They received an easy group that they topped, they drew a relatively easy quarterfinal, but all of their prospective QF opponents would be easy (outside of EDG, unfairly seeded into a group of death because LCK 3 was T1).
So swap T1 and Gen.G at this tournament. Seed the teams accurately and suddenly everything looks correct.
This is a long-winded way of saying that I don't think the Worlds format is bad. No system is perfect but I think the Worlds format lands a good compromise on many fronts and I don't want to see it changed. The best teams cannot play each other until at most semifinals, no matter where they come from. Any two teams can get out of any group and will automatically be placed opposite one another. Any two sufficiently good teams in different groups guarantee that they dodge a quarterfinal bout. A 2/3 chance dictates that they won't meet until the finals. Anything short of that is an upset. KT Rolster arguably got robbed of a deeper run because IG inted their group stage. But I'm not convinced it's up to the tournament to salvage that. If KT were good enough, they'd have won that series and made finals. Instead they get forgotten like so many other teams who failed to pass quarterfinals. It was a rough draw, sure, but it turns out you still have to win if your goal is the world title. I think that's fine.
As a final point, I think double elimination makes a lot more sense when you care about more than one team becoming the reigning champion. I like the LCS's summer playoff format where that bracket itself qualifies the teams for Worlds and so a lower bracket run makes sense for finding the top 3 finishers.
