Hi there
We are getting very frustrated by players who are using a exploit/bug that makes them invulnerable whilst able to attack you defending Godstone Quarry (also other areas similar.
They stand near the hill at the back of the quarry and become invulnerable.
two things spring to mind.
1) If they are invulnerable so should you to them.
2) They can just stay there until you get fed up with waiting for them to come out and take the supply camp.
We have reported the players who use this exploit but nearly all do it.
I enjoy WvWvW but this kind of exploit (aka cheating ) really makes me and others mad.
Great game btw and fantastic Halloween events :-)
