Yea its horrible.
The core issue is just the amount of time they have since they have to fit it between t1 stages.
Formats with 12 and 14 teams are surprisingly difficult to design - even more so if you want to limit yourself to as few games as possible
But the current format just isnt acceptable so they HAVE to iterate.
Current format is FAR too seeding dependent... which is a problem when you cant seed since teams dont play each other before the international stages.
Id personally expect we see 3 games at the same time next year in order to allow for more formats.
