You MUST have glider in order for this to work. Glider is a bot program.
This profile:
Farms: Crystallized Water (which is turned into eternal water), Coin, Frostweave cloth, Greens, occasional blue and epics.
Starts: In The Argent Stand, in Zul'Drak. This will work for both Horde and Alliance. This area is not crowded at all on my servers, and is a very smooth run. I've went 800/800/0 a couple nights in a row.
Gold: It makes ~1,500g per day
XP: ~150k
I ran multiple toons on this profile, both ranged and melee and did great.
I've leveled from 74-80 at this spot, though from lvl 78-80 it really starts to slow down.
Your character will go from buying food/water at the innkeeper, to repair, then off to the grinding area, which is just by town, about 20 second run.
In order for this to vendor successfully, you will need to do a few things:
1) In your glider options under misc, tick 'Stop when bags are full'
2) Your food, water, and hearth stone must be on the same bar
3) Your Food/water has to be something the Innkeeper sells and if you are melee you must also choose a water or glider will bug out.
4) Make sure your specific food/water is recognized in your Keys>common options, or glider will bug out
5) You will need a restarter, set it to restart in five seconds if glider stops.
