Due to the lack of players at certain time zome, WvW can be very difficult for certain group of players who is running around alone and getting chase down by a 50 players zerg. Unfortunately, not everyone has the luxury of time to play 24/7. No one wants to play 24/7 either, I tried it during the lockdown, log in long hours will kill your computer, it's not a good thing. Other players need to filled in in this cooperative game mode, there are things need to be upkeep and objective needed to be defended. When you log into WvW and find that no one is around to help or play with, you will mostly just watch a keep that took 10+ hours to get a waypoint smooshed and flipped to another color and it is not fun at all.
So where are we going to filled that gap?
Link servers not region bound for WvW
IE: link EU server with NA host and vice versa. That's where the population gap fillers are!
