Guild Wars 2

On Desolation right now, we just failed a Grenth event on the last part, after killing the priest. There was a Champion Risen Spider that took a full minute to display at least, happily mowing down people left and right helped by her seemingly endless legion of culled out suicidal risens.

I kid you not, there was only 3 mobs visible at most during that full minute and judging from the damage received and the number of players there must have been 20-30 of them around in reality.

Yup, was there. An invisible mob just wiped out the entire room of players and failed the event. ANet, there is a reason the Temple of Grenth is not completed and open on any of your servers, fix it please.
