We are currently working on the difficulty of the Assault Knight fights; I realize that sometimes its hard to get a full overflow or that there are non peak hours where server populations will be lighter. Hopefully with the difficulty changes, it will also make it easier for a good server to get ‘Six Minutes to Knightfall’.
I think you meant to say “full population server” instead of good server.
The developers and others at Arenanet need to get it out of their head that challenging and requiring huge numbers arent the same thing.
