Why does a server die, why does a game lose its players

"Waiting for players to join." Does that sound familiar to you? Of course it does. Because it happens so often, especially on official servers. As soon as there are 7 players on one side, it says waiting for players. Even if on the other side are 9 or 10 people, so a total of 16 or 17 players on one server. Nevertheless, the server does not start. for other games, that would be a completely full server. Think about Counterstrike or Rainbow six. It's ridiculous. Someone who reads this on the character selection screen, is leaving. And others who see leaving player, lose their hope and also leave the server. That is one of the reasons why the server dies and this is the reason why a game dies. And why are there no 16 players servers? What still has to be criticized are the sometimes extremely short rounds, long joinin times & waiting times after a server has started. You stand on the field for 60 seconds and you cannot move. Why are there so many annoying elements in the game and why weren't they removed ?
