Hi, I just got an idea to help FS. It is true that guild Casu, with there 3000 canadian members is breaking WvW.
Maybe you should improve Xp and loot ratio when you make WvW kills. So maybe all the PVE players populating FS ‘at night’, go WvW instead of puzzle or dungeon.
Then they may try to defend themselves when no ‘big guild’ is around.
