I know it already has been mentioned in another thread, but I think the issue is worth its own thread. So everyone (even PG) can find it better and quicker.
It looks like nobody has the versus button or the side quests for a guild battle event at the moment. So PG tell us please what has happened this time. And I really would appreciate to get a reply from someone who works for PG this time. That's simply a question of politeness and respect.
