I like to farm in felwood on the toxic horrors. If you have a decent amount of epics and you have ice trap fingers you should have no problem with horde there just don't use a trap while killing mobs, use it to catch rogues/warriors or any other ambushing class. The mobs in felwood are also around alot of bushes and things that drop some very nice buffing items if you open them. Farming elemental waters and elemental Fire all that stuff sells for alot of gold.
