The obvious tip is to manage the time you try to get into the server.

If you are attempting to get to a popular server, then, of course, you are not alone. The waiting hours can extend severely. What you can do is to choose the time when it is not loaded, maybe try the early morning or late night. Are you willing to sacrifice your sleep? Then try to log in to another region’s server where the time zone is different and suits you most. 

The second, and still more obvious tip is to go to the not-so-popular server.

You can see it in the “Population” attribute of the server on your screen. Amazon already made some new servers and works on the option of transferring to the server where the queue is decreasing. 

Well, if you successfully logged in to the game but you need to take a rest, you can be logged out the moment your character becomes idle. To avoid that many players became the wall runners, as the server registers some activity from you and keeps you logged in.
