From using a Wrapped Entropy Serpent Spine with my rogue and Blind with my beastlord i have figured out that blinded mobs will only run if the person who is highest on the hate list is out of melee range. Blinded mobs also don't hit anyone else but the person highest on the hate list. This could probably be used well in a group because once the mob is snared and blinded none will have to worry about gaining too much agro becuase once the main tank has agro anyone else who gains agro will just cause the mob to walk away. This could also be used by mages to pet kite much like a beastlord would...Beastlord tells bet to stop taunting, dots to gain agro and blinds...mob will run with pet beating on it.
