if the mob is agressiv and don't move you can try to use quest type "FollowPath" (and go to mob position).
You can also try to filter mobs to run code like:
wManager.Events.FightEvents.OnFightStart += delegate(WoWUnit unit, CancelEventArgs cancelable)
{
if (unit.Entry != 1234 || !Quest.HasQuest(1234) || unit.InCombatWithMe)
return;
if (unit.Guid != 12345645678)
{
wManager.wManagerSetting.AddBlackList(unit.Guid, 1000 * 60, true);
cancelable.Cancel = true;
}
};
(complete the questid, entry and mob GUID, GUID is normally the same on all server and unique)
