Excuse my English I am using the translator!
Well… My suggestion is to put a controller for idle people on the servers, for example, if the person staying more than 5 minutes away (still in the game) the game automatically expels it back to the character selection, it would improve the overcrowding of servers and avoid having to login queues. Walking through the maps I noticed that always has a 3 or more idle people!
Sometimes the person left the game open and went to see something else, and it harms other players who want to play and have to wait in line!
I hope this can help, and thank you!
