The problem is that you have teams like Qatar or Cameroon in the top 24 of ranking which is... not realistic. They have much bigger chance to qualify than FIN, CZE or EST who are probably stronger than them. I'd say Australia is also stronger but they screwed up losing to Qatar in 2019 OG qualifier so I guess they deserve to be out.
CAVB and AVC will still have continental championships right? The rankings will fluctuate there. Can't really control the FIVB's want for representation either.
COVID didn't really help the new rankings being released. Looking at the Golden League, the Czech's and Estonian's could've done better there to secure their spots. It looks like Finland didn't even enter.
I don't have any expertise re: the men's game.. but if they "deserved" (i dont like phrasing it like that), they should've done better in those events. Looks like none of the three teams even finished in the top 12 of the last Euros, where there were a lot of points to be gained/lost.
