WvW map completion is not a joke. The problem is for the PvE crowd is they wait do WvW map completion last, after getting all the PvE maps done first. It is really easy to get all the POIs and Vistas for the color that your server is currently, unless you are matched up against a server that constantly steamrolls your side during the hours you play.
My suggestion to the PvE crowd is to go into WvW, get all the POIs and Vistas for your color, and log out. Resets happen on Fridays, check then if your server has changed color. If not, wait another week.
I wish I could feel sympathy for you, but I simply cannot. There have been countless times where I have seen our server be assigned a certain color that we haven’t been for weeks, and then promptly notify guild members to suggest they pop into WvW to grab needed POIs and Vistas. The normal response? I’ll worry about WvW after I finish all the PvE maps.
Another option would be to, oh say, hop into WvW and join up with your fellow players from your server. I have seen many times a commander lead a zerg of 20+ to take a tower or keep because one person needed a POI.
