Maybe some already do it, but here is a relaxing farming spot in north kryta province. I do this when im bored and want to kill stuff.

The run takes around 20 minutes maybe less, depends on how distracted you are xD.
The drops:Feathers: around 90-150+ if lucky + scalps
Gold items
Runes
White salvageable for Tanned hides, iron etc.
Dust if you take the little quest that spawns like 10+ nighmares
Scales
Gold ~ usualy around 1k-2k+ depends on runs.
Tomes
Elite Tomes from bosses. (monk, war, mesmer,ranger) usualy 2-4 bosses+
Mobs you will be killingTengus
Skales
Ettins
Mergoyles
Nightmares
Avoid the imps if possible, they can be killed but they can be a pain sometimes.
The buildUsual Spirit Spam x/Rt
Sos, Vampiris, Spirit of Blood Song, Pain, Shadow Song, Armor of the Unfeeling, Spirit Leech aura + optional, can be healing/running or w/e you want.
I bring hexer's vigor along for regen in case i agro. I use my Necro for this run, can be done with any class as far as i know.

Here is an example of a run i did, i skipped the ettins in this one. Started with 0 gold.

Might not be the best farming, but its fun.
