It's not the progress people are laughing at, it's just the general way of how your guild presents itself to the public. It looks like a joke, the way your guild members reply here is also kind of a joke. It just looks like you guys are trying to conduct yourselves in the worst possible manner. No wonder nobody ever takes you seriously in the world first race. It's a meme every single time.
You say that with a sense of pride but there's nothing to be prideful about, though? The US raiding scene is a fucking joke compared to the rest of the world. The only reason you ever see yourselves on the first page of the rankings is because you get to clear the raid a day earlier. If EU and US started at the same time, you wouldn't even be on the first page, or at the very best, you'd be at the bottom of the first page, lol.
