Heheh, rooted, indeed. I found a heroic cyclops at the far east of moors, and as a brand new sorc I thought woohoo and cast my root. I made fast steps as I saw the word immune!
KC can be soloed by a wizard except for the last named with the clickies and maybe Ventrek, with tinkered items you can save much time by skipping trash-mobs.
Some nameds in Chardok and Seb are also possible...just try it
The general rule really is: If it's rootable, it can be soloed/duoed
