100% verified that she does in fact spawn in the normal version of Old Commonlands (not just in the instance version). There is a hill at -160 -980 that has 4 Obliteration mobs on it, covered in purple mist and has a lot of the mutated/enraged/soulrend mobs popping on it. She spawns at this location.
EDIT** After camping this area for awhile, I have found that she can spawn in all 4 spots on top of the hill.
Immune to run speed changes.
