I don't have a log to post but Rogues can wreck in the arena.. I average around 100-105 seconds and if I have bad luck and get a few things wearing plate it could take 130-135 seconds. I am a 3x stalking and hiding rogue archer but when doing arena I just do open archer. I did about 1k runs this past duskruin and think I got injured like 3 or 4 times. I have max ranged enhancive, max dex, agility and was running with an AS of 658. Can pop it to 700 if needed with some magic items I have but its just not needed. So in my opinion rogues do great in duskruin arena.
