I Will start:
Guild will finish top 3.
So possible I don't even think it's a hot take. Xerxia could once again have Optics number. LOUD and FPX are two other top 4 teams that at least one of will most likely be facing OpTic. If any seeded stuff goes on (for example how out of the Major regions NA got 1st last masters, BR/LATAM got 2nd, APAC 3rd, EMEA 4th) It makes it even more likely for one of those two to be in their bracket. DRX is also a problem. They had never functioned as well in Korea as they had in Stage 2. This is the best DRX we've seen, and they could very well beat OpTic.
Side note: Major/Minor region is NOT based on skill, but based on Masters spots. Japan and Korea send 1, thus minor regions. EMEA, LATAM/BR, NA, and APAC are the major regions as they a) send more teams and b) contain more teams in the region.
TL ; DR - Xerxia beats OpTic a lot, FPX and LOUD are on OpTic's calliber, DRX showing their best and their not best almost beat OpTic.
