At least Grey Host PC EU. All keeps that I've seen are surrounded by siege weapons so u cant put any more down to siege because you are over the siege limit and furthermore they fill the spaces where u should put them anyway. This means the situation in bound to stay as it was before patch so PVP is UNPLAYABLE.
Its a game breaking bug!
I wonder when the servers are taken down to fix this. Probably not too soon as PVP is not a priority, unlike ToT.
