Ones near zone in are socialable, but also snareable and rootable seem to have low MR. I killed a few but didnt get any drops, biggest problem was splitting them w/o an FD or indoor harmony spell.
the ones at the zone in con mostly blue/even to a level 65. the hit a necro in the 900+ range (did not wait to count but i think it was tripple). best thing .... they dont sumon > kitter prey ;). (walk relativly fast while snared with a 75% snare. got about 7-8 secs to cast a range 200 spell bevor they are in range to hit you.)
