A term referring to the strategy a player uses to "herd" one or more mobs to a specific location, making it easier for team mates to attack them. Herding is especially effective in teams with aoe effects, because aoe damage can effect the entire mob at once. Typically a Tanker will herd because they can very effectively hold aggro. However other Archetypes such as Controllers with pets that aggro, can be almost as effective as a Tank.
