tried taking her down earlier today with my 51 wiz, snare went Unresisted, yet she stayed at same speed, so watch yourselves if you're trying to take her down.
For all you pally's out there looking for a way to impove faction, this chick is it she has a great spawn rate and is fairly easy to kill for either a gorup of 40+ to solo at level 52. I also did the Rat King quest multiple times -- Went from Dubious to Ally in just 8 trys down into the tunnels. Good luck
