If your issue is about movement, there are two options that can be useful for helping the players. First of all, if your problem is that your main hero cannot move at all, then this may be caused by an internet connection error or maybe some other reasons why you cannot connect to the server. Change the position where you are located and try playing again. The second solution which can help if the player's character moves too slowly over the map is to go back to the main menu > Settings > Select "Reduce Quality" and this should definitely speed up the player's movement.
