It’s pretty simple.
On Friday before the WvW reset, you transfer 40-50 people over to your enemy server.
You then go into WvW with those 40-50 people, and sit in spawn doing nothing. Actually no, you go PvE the entire time, and camp the jumping puzzle, so any of your actual server’s players that try to PvE get stomped and don’t come back, forcing them to actually take the entire map. You then rotate through each map, displacing the fighting force with do-nothing players, and win. You will have to make sure no one AFK’s for good, or find some of the ways to avoid being kicked for inactivity (mobs attacking you every now and then works I believe).
I swear it could work!
