K, so again, the very unscientific report for 1 hour of farming this clickable grave mound is:

approximately 35-40g in silver and sellable greys
1 blue Rare
11 Greens for DE'ing
Easily 100+ Runecloth (had to Bolt them as we went along, too much bag space)
about 25% of my level 55

So, if you've got this quest, or have yet to get this quest and are looking for an ok spot there ya go ~

I myself am going to hang on to this one for my 50s I think. It's just too easy to not do.
