Back to the Wall

Modified an existing macro made by 883272 for the achievement Getting Around with the Shadow-Pan

/run local a=40620 print(format("\124cffFFFF00TO DO for %s\124r",GetAchievementLink(a)))for i=1,GetAchievementNumCriteria(a)do local d,_,c,x,y=GetAchievementCriteriaInfo(a,i)if not c then print(format("%s %d/%d",d,x,y))end end

This can be modified for any achievement that Blizzard's tracking pane doesn't "track" by changing the achievement id and that's it!

Here are the Arathi Prisoners locations I found for Back to the Wall. I would recommend doing it on a level 70 character due to scaling and the achievement is also included to your warband.
These two quests you need to do Here's the Plan & To Arathi's End to be able to pick up Invasion Disruption
You can also do it during Special Assignment: A Pound of Cure

Ok so if you have come here for more information on how to do it here it is : You have to rescue webbed arathi prisoners in the north eastern zone of Azj-Kahet.

This is an extremely annoying achievement to do and it will take some time. Ideally you do it during the side quest Invasion Disruption Quest. There are 8 webbed prisoners that you can rescue and they take about 2-3 min to respawn. Some of them if not almost all(5 of them to be precise) are surrounded by high level golden dragon mobs that charge at you making it extremely painful because killing them also takes time.I would say abuse the fact that during the quest Faerin taunts the mobs.
The webbed arathi prisoners are not unfortunately personal so that means if someone else is in the zone they can take it from you. If you fill the bar the prisoners are not interactable anymore,at this point you either abandon and re-take the quest or just be in a raid group.

All in all awful but i'd say get it done during the quest god knows how it will be during the WQ when there will be multiple people interacting with the prisoners.
And don't forget to use the command from @Realkell to check your status on how many you freed.
