1]get the Escape from (forgot the rest) quest that you get in upper Tol Barad to escort a npc of your faction.
2] spam the npc to desired amount
3] control them with /petattack and /petstay
4] juggle it off npcs so they dont despawn and run back and forth around you (found that the other factions npc works well as its 5yards away)
5] send to to attack nearby players

spent hours doing it as friend controlled them and i acted as a scout to send them above to attack horde. you can drag them all over too if you have something for them to attack and chain off of. we got as far as the horde questhub but the guards hit too hard. might be hotfixed soon/next patch depending on how much blizz cares about the people who opened tickets QQing.
