I finally caught up with Brinstar from Acid for Blood in Guild Wars today, and we took on the last mission of the Prophecies campaign together, Hell's Precipice. This was my second successful time through the mission, and I think her first. My last completion of it was with a pretty decent guild which I was briefly a member of. It's amazing how a level which is such a frustrating bore when tried with random groups becomes so much more fun with skilled players who you actually have some reason to know beforehand.
I still have to do the mission at least one more time, though - I forgot to fill in some of my map. 8-)
