In my case, the list so far:
Feerrott
HoT
The Well
MN
MC
Within those zones, Feerrott and HoT are naturally the easiest, followed by The Well. Adds are annoying, but not unmanagable... twincast & the gargoyle with Silent Casting and the two bolts is your ticket there, healing the pet while the DDs are refreshing ( if you aren't 90 yet, you are gonna be one happy mage the first time you get a good crit with the Spear; it almost makes up for the traditionally crappy heal.

So how about you guys, where are you hunting?
