This is posted in Policy Explanations, but I think it's important that everyone be aware of this policy who might not see the post there.
A clan Master may order a mob to follow himself or herself only.
He/she may not order a mob to follow any other player or mob.
In the very near future, you will find there will be code implementations to address this problem. Mobs will no longer respond to an order to 'follow' once you have ordered a mob to follow you. That is important to note, because the mob also will not respond to 'follow self', you will have to group the mob and ungroup it to cause the mob to stop following you.
A clan master may lead as many mobs as he/she likes to any one spot (stacking) within their home zones. The code will not allow a master to lead more than one mob at a time out of its zone of origination, so stacking elsewhere should not be an issue.
Ordering a mob to follow other mobs or other players is abuse of master powers and the abuser will be subject to any penalty the clan members or staff deems appropriate including loss of mastership.
Creating massive super mob groups of mobs that all move about together, or creating stationary mob groups by ordering otherwise roaming mobs to follow a stationary mob, is not considered acceptable and will result in zaps. This was not one of the intended benefits of being a clan Master, and the mob leading ability was not granted to masters for that purpose.
