Peppy, I'm just going to point out, regardless of what direction you plan to take this in, your current actions and attitude about the situation are the problem.
Telling people who play the game competitively to "just play for fun" is a huge insult, and I'm pretty sure you realize this, but the only reason osu! can be as successful as it is is because of the competitive nature of the game. Without overall ranking or leaderboards, most people would put maybe a few thousand plays into the game. When someone gets seriously into the game, they're always trying to better their skills to meet goals, but without the competitive and community aspect of the game, it wouldn't be so fulfilling. I think telling players to just relax and play for fun is dismissing all effort they've put into getting better at the game, and it really pisses me off, to be completely honest.
Another thing is, while you keep saying "calm down, it's not complete, I'm still making changes", every single iteration of ppv2 I've seen so far is just as bad as all of the others in my opinion. I have not seen any changes in what I would consider a positive direction, so I'm very wary of where you might be heading with this. It's always better to throw out the criticism early while changes can be made, then let it fall to deaf ears too late (although, some would say the criticism is falling on deaf ears anyways). Some people are definitely getting way too upset way too soon, however there is nothing wrong with being vocal about the changes. If you make something public, it's public - even if it's in testing mode, people will give the feedback to help steer it in a positive direction, and you should listen to and accept that feedback without just dismissing it by saying "it's not complete"
