I do not take credit for this.
i read this on deathsoft like 2 years ago. I am simply writing this up because i doubt anyone would search for that =S.
The mobs outside RFD (or RFK - The lower level one) are shown as non elite level 23 - 26s, however they have about 2k hp and hit 100s, so whatout - i normally go at 30, depending on gear.
anyway - each kill you get about 20g, 4 - 5 mobs. so 80 - 100g. Which compared to the 14s a mob you get at 30 definately helps.
This is only really usefull on low rate servers, as you generally quest and can go from 20 - 30 in like 5 quests, earning almost nothign money wise, so its helpful for mount... and so on.
good luck and have fun - I do NOT take credit for this.
