Man, I remember when 2 years ago I was like: "Why should I even participate if there are completely no chances for us?". If that's the reason why other countries aren't taking the part in this TWC... that's just sad, as guys explained above.
I know, that for lower ranks getting 'rekt' by Godlike teams wil not be fun at all, but that's not the point. It's not only about playing. Since the matches will be livestreamed (I hope), you can always watch others, even cheer them up and all this stuff. I know you guys also have friends all around osu! and you will be able to watch them struggling in hard matches.
But... not participating because of "having no chances" is really a bad idea. I realized that myself some time ago, even is our country is always knocked out after leaving the group stage. Also, playing in multiplayer with some random people is not even close to being the same as TWC. Of course, you can gather some people and play with them, but still - it's not the same.
From this point, I don't want to insult anybody, but stop crying and get into TWC. Who cares if you lose even on first match.
IMHO, TWC is an event where you can just forget about your rank. Am I just naive too?
