The arena should be like this, you come in a rank class as a novice, this has a beginning and top list. If you come above the top list, you will enter a different rank class, a higher class, etc. If you have proven yourself with your performance, you have to stay in that class. If you get better in that class, you go to a higher class. and stay until you get better.  but at least you won't relapse  in a lower class.

 Someone with a strong team should therefore never be allowed to play in the lowest class.

 just like in school, you are not enough you should stay put. if you passed, you go one class higher, but not lower. And then you have a list in that class who is the best. 

This is a very reasonable thing
as in normal life.  

And then there is enough motivation, to compete for in the classes where you are to get higher, or to be at the top of the list. 

Then most people would be satisfied and no more complaints. 

=================================================

if you were under karate, and as a rookie you had to play a competition against an advanced player, and you keep getting beaten up, you would also stop. 

Or you have to keep racing with your Lada against a ferrari. and if you always have to experience your loss, then it is not surprising that you are going to stop. Nor would it be normal to just keep going, doing the impossible. A Lada should race in its own class, but not against a Ferrari.

this is the same with this game. 

That's why there is a lot wrong in the game. 

Are you going to throw money in a gamble machine when the gamble machine is broken, so that you can never win an amount of money? Only a fool would do that .
