So this is the Map
This requires a two man team. A hunter (with a cat) and a rogue.
You have a rouge stealth to the first vein [Link] (The drops of arcanite have to be much higher out of 10 runs i got 4 crystals, could be pure luck ^^) in zg . Normally before the Gurubashi Bat Riders that explode. Then have your hunter send in his cat stealthed to the rich hakkarian vein and jump out of prowl and aggro all the mobs. the rogue with 300 mining has about a 10 sec window to mine the vein while the mobs guarding the vein are chasing the hunters cat. Run out rinse and repeat.
It takes alot of pratice you can get the runs down to under 5 min and also loot the voodoo dolls:
Mage
Warlock
Hunter
Paladin
Warrior
Rogue
Druid
Priest
Shaman
Souldarite [Link] also drops which can go for 50g each [35% CHANCE]
