Oh jesus, the mirror halls. No, no, no, NO!! I grinded the merrevail deed on some characters and eventually gave up I think, 360 kills on just one char is way more than I can take in a lifetime (considering there are like... 20 of them in one run).
First time I did the instance was back then, onlevel. It took us over three damn hours to get the mirrors in the main cavern right, and we almost gave up like ten times.
It always sucked, and always will suck hard. The concept is good, and I mean it, but the reality is HORRIBLE!
