Well I mean even if really low ranked players (around 5000) sign-up they won't actually end up playing for a few reasons:
1. Their country will have plenty of good players that sign up so they won't get picked by team captain
2. They are actually one of the top in their country since they belong to a smaller country, but their country will:
a. Not have enough players high enough rank that sign up to form a team
b. Their team won't be in the tournament as not one of the top 32 countries strength wise.
Honestly the 5K rank or higher is kinda silly. I am rank 1.2K and I know for a fact I have no business signing up for CWC. Not that US would take me on the team but I'd get demolished.
since when was people with rank 5000 have 1k pp? they have like 5.5k+
...Has that even happened before?
