then i suggest you go and try it

and the mount thing to stop your pet from dying works so yeah :P
if your pet is in combat and you fein you stay in combat but your off threat lists
if you tell your pet to follow to stop it from attacking and fein, aslong as its target is still alive youl stay in combat
sorry but im right, i just may not have conveyed the idea of it properly
say your doing the quest in blades edge where you have to kill the named guys, plus two "sobre" elite guards and 2 non elite adds
send your pet in, start shooting and hit mend pet, the adds come for you, kill the named and fein, the adds then go to your pet,
your pet is in combat and you cant mount, if you then hit passive, even if your pet is already on passive it will take you out of combat so you can mount
therefore saving you mana to rez your pet, time and pet food
