It depends on class a bit as to how much use farming money is.
For example if you are a necro then farming money is a waste of time. Better just to level up as fast as possible.
Mellee type chars probably have to do a bit of farming for gear.
I don't like EC particularly. I find the level range of mobs to great and getting into trouble a bit. There are a couple of spots where it's pretty good though. The north west corner by the huts is pretty safe from wandering kos mobs, and a zoneline nice and close.
For just levelling I rather like NRo. Not much money but the mob ranges are pretty well graduated from north to south. After that I usually go to oasis which is crap loot, but good for getting a group. As a mellee you probably need to farm some money for this though. As mentioned wisps are great for cash, but watch out because the guards wont save you from them. The "going postal" quest used to be good on live where you could use the POK stones. Now you have to run them you probably don't one that needs boats. Here is a list...

Felwithe to Kelethin sounds decent, as well as west karana to qeynos.
When you're a bit higher level, theres good money to be had off the karana bandits and the bandit sashes. Turn the sashes to Chesgard Sydwen in the paladins area in Qeynos. You get a bronze weapon for each sash plus good gold. The bandits are an amazing camp if you can manage to single pull them. You probably need either a druid with harmony or a high level char to break the spawn.
When you get to 20ish you can camp the hermit in SK. I think he is about the lowest level mob in the game that drops fine steel. Run directly north and sell them at the centaur camp. Besides great money he is an easy kill with a crazy fast respawn timer and there are no adds. Good till 27ish.
