So after getting the Bloodsail Admiral title I wanted to fix the reputation with the Goblins as reputation with them gets totally destroyed and I wanted to be able to use the Neutral AH again and buy some Noggenfogger Elixirs too...
Then I found out that I had to buy like thousands of cloths for some repeatable quests. Screw that.
AFK farmed my title killing Shakes O'Breen so I thought I could find a farmable NPC to get Goblin rep back.
So I found a NPC that is on a fast respawn rate and we will use the terrain to hide us, giving us that extra protection.
Get on top of this palm with your flying mount.
Result:
Now open up _Keyspam or download from here Filebeam - Beam up that File Scottie! and edit the settings, these are mine:
That will spam "R" key every 15 seconds, and this is the macro I use:
/target "Good-Boy" Bruce
/cast throw
/cleartarget
/cast vanish
As you can see Im using a rogue for this but any class should be able to accomplish this with ranged attacks, ask in this thread and I'll help you with the macro you need.
I recommend _KeySpam because it spams World of Warcraft window only, so you can use your computer to do other stuff.
Enjoy.
