I have a feeling players could gain enjoyment if the way players are spread in maps was different. What if the player distribution on PVE areas would not be according to WVW servers but just by the amount of players. Meaning when a player joins a map, regardless of what server he is in, he is placed in the most populated instance of that map, only when that map is full, any player who attempts to join will go to the second instance on the list, and so on and so on. For those who played gw1 this was how it worked, and it was great.
This could only be better if we would also have a drop down menu of all existing instances and we could jump from on to others as we do in gw1. With the limitations required to avoid exploits on meta and world events, same as we have now.
Why do i feel this is needed? Happens many times i login to the game, my map is empty, i play and while and get the message to jump to another map, i do that and the next map is a little bit more populated, after a while it's time for the meta, i join the meta group in lfg, jump map again, and that map is super populated. Makes me think, why did i login to an empty map, if there are maps with lots of people? Imagine those players who don't even join meta groups, they think the game is dead.
I am near sure something needs to be done, change how people are creating empty instances. Just put everyone on the same instances.
