INFO:
In Ashran, there is an Achievement: Rescue Operation - Achievement - World of Warcraft
This basically requires you to farm keys from some no-so-easy-farmable-mobs and use them to interact with some cages in order to free the NPCs inside.
If you free an NPC, you get 75 Honor and 25 Conquest Points.
Info: Standing next to the cage, if somebody else opens the cage, still grants you points + acm. progress.
Exploit: This also works in Crossrealm/Phased Ashrans, that means if somebody else NOT EVEN INSIDE YOUR ASHRAN opens a cage you will get points, but it doesnt count towards the achievement.
Notice, that there is a Prison Guard which can drop a key (3%) and always dropps around 10 artefactfragments.
Proof: You can see, that I farmed the Prison Guard and he dropped no keys. Later i realized, that I got points which made me post here and right now.

+ standing inside the prison will always grant you a lockbox when your group kills the faction leader.
So you simple have to be afk inside the prison (over night i.e.) and on the next day you will have maybe 10 extra lockboxes and maybe capped honor/cp
