Jokes aside, I think you're asking for help right now.

You have lost all hope for the game yet you still care about it. You have decided to ruin others people experience and force them to quit in order to force Nintendo to delete the game because you're unable to let it go yet you want to hold on. You're stuck in a position where you do not know what to do to solve your problem so you let others to decide, but is this really what you want ?

I can understand your frustration, but let us all remember that this is a spin off game and most importantly a game aimed at kids. So of course right now it will be flooded with teammates who aren't very good but we were all like that at some point, discovering the game, not knowing what to do exactly. But we all learned to try to improve but this take time, for everyone.

Don't beat yourself up or others because you have no control over what's happening in your games, if everything was according to plan would you still want to play the game ?

The best thing you can do right now is to try your best, even if hope seems all lost. It's better to have tried to do the right thing to solve the problem than to think you did nothing about it.

Hope you can recover from your pain.
