For most people, farming Heavy Junkboxes for Ravenholdt reputation is the worst part of the Insane in the Membrane grind. There is a way to speed it up dramatically, though, that is available to most players.
All other things being equal, it’s my current belief that the best place to farm Heavy Junkboxes is the Greengill Coast on the Isle of Quel’Danas. Unlike at the Fields of Honor, you can farm pretty much continuously here. If only the murlocs would stand still…
This weekend Hellrazor#1519 clued me in to a way to farm junkboxes much faster from those orcs at the Fields of Honor: Simply pickpocket one square of mobs, kill them all, and then realm hop. This completely eliminates the several minutes wait you would incur when farming here normally, and can more than double the number of junkboxes you can get. Hellrazor told me he was getting 130-140 per hour, where normally I expect to see 50-60 per hour at this location.
To realm hop rapidly, you will need an addon. My current favorite is Cross Realm Assist, which has a single-click realm hop button that cycles you through every single available group. Pickpocket a square of orcs, click the Quick Join button, and you’re on a new realm with fresh mobs. Lather, rinse, repeat until you fill your bags or you can’t stand it anymore.
There is a catch, though: You’ll need cross-realm groups to cycle through. If you’re on US United States, EU English or CN China realms, this is no problem. Each of these groups of realms has plenty of cross-realm groups at most times of day or night. But in others, such as US Oceanic or Latin America, you may have difficulty finding enough cross-realm groups to make this work reliably. If you find there are few cross-realm groups available to you, then I recommend pickpocketing all four squares of orcs before realm hopping. If there are no groups at all, you’re probably better off to go back to Greengill Coast and pickpocket murlocs.
Let me know how this works out for you, and if you have any other ideas for speeding up the grind, feel free to contact me.
