Currently, all LA servers after S14 has been grouped in a single giant bracket. Servers in other regions are divided into multiple smaller brackets. This doesn't seem right. I almost feel like someone made a typo when setting the brackets, and put S14 - S599 instead of S14 - S59 (which would've been a much more fair bracket).
In the LA Space Time right now, rank 100 - 400 is just a sea of 45 - 50k players. There are a total of 4 players from S2* in the top 200 for point ranking, zero in top 128. There are zero players from S3* or newer servers in the top 200 at all. Even S1* players in the top 128 is pretty uncommon.
This bracet size feels very abnormally large. Other regions have servers less than 2 months apart in age competing with each other; while LA have servers over 8 months "competing". There actually isn't all that much competition for servers 2* and later. There is simply no chance.
