Hello, gentlemen, this guide is mostly intended for Horde, since the mobs are only in Horde's Base, but it is possible to get there as Alliance, since you are a stealthie.
How to get there
From Horde Base:

From Alliance Base:

How to Pickpocket them:
You will be pickpocketing the Wildpaws:

For this item: Heavy JunkBox. They sell for roughly 10-20 gold each on my server. If you have WoWinfinity available, you are able to go at 100% speed (Ctrl+2) and still be able to pickpocket them. You must have autoloot enabled.
To pickpocket them use this macro, it will select the nearest humanoid, pickpocket them, then deselect, so you are able to spam it as fast as you want:
Code:
#showtooltip Pick Pocket
/console targetNearestDistance 8,0
/targetenemy [noharm][dead]
/cast Pick Pocket
/cleartarget
/console targetNearestDistance 42,0
From this cave you will get roughly 5-10 Heavy Junkboxes (worth 75-200 gold). If you still want to make more money go to the mines located here:

and spam the macro as quickly as you can, if you miss a mob it doesn't matter. However, these mobs have a buff which basically does AOE damage to anyone close to them for mroe than ~3-5 seconds, bringing you out of stealth, and aggroing them. So, with the mines go as fast as you can spamming the pickpocket macro, and using sap and distract if needed (You can also cap the mine if you want to help your team). There are literally 100's of closely packed mobs here, so you can get 20 junkboxes if you do it for most of the AV game (200-400 gold). However, as I stated before the drawback is the AoE damage.
Also, I prefer Subtlety spec to do this in, since you get faster stealth moving speed, and Preparation gives you a second Vanish if you mess up alot
.
How to sell the Junkboxes:
Contrary to their name, almost everyone seems to want these junkboxes, since they are used for "The Insane" Title. Simply go in your capital city/Dalaran and click this macro:
Code:
/2 Selling [Heavy Junkboxes], pst with offers!
Feel out the economy for these bad boys, however, don't sell them for under 10g, after a few times of doing this, there will be someone who wants to buy them in mass amounts, agree to send them COD to him, and you can rake in the money!
After 3 rounds of AV, I made 700 gold, and I was also periodically checking facebook, and talking on IRC. You also get a bonus 5-10g from the spare money you pickpocket from mobs.
Advantages:
- 300 gold per round of AV if you try
- Free Honor
- Free EXP (If you do this while leveling)
- Achievements for BattleMaster
- You won't get flagged AFK
- If you get tired, you can grind on the Wildpaw for bonus exp (usually double normal AV exp))
Have fun Pickpocketing!
