Game crashes (black screen), cant login due to server overload, lost spot on server

As the title;
Game crashes randomly, just the game nothing else, screen goes black, cursor works but have to shut it down.
Afterwards trying ro reconect, cant login due to busy servers.
4th attempt worked, but apperently took to long so now Im in a que with 16000 people before me.

As the game has been around for a couple of years, shouldnt problems like these been addressed earlier?
