Fear actually can trigger social aggro, if the mob is close enough others of its kind when it recovers from the fear.shrike wrote: The IMO safest way to pull a mob out of a group is to fear it (don't hold the spell). This aggros it, but does not activate the social aggro of nearby mobs so you can let it follow you to a safe location.
But still fear is a pretty safe way to pull, as the fearing itself wont trigger assists, usually the mob is away from the herd when it recovers, and it won't trigger assist if it runs through the herd on its way to the caster.
Afaik taunt can trigger assists.
