Sin Monk or Ele to Farm with???

I have heard that these three classes are the best classes to farm with.
Sin for the Perma SF, Monk for the 55hp or 600/smite , and Ele for the fast nuking skills and defensive spells such as mist form. My question is which is not in jeopardy of being nerf'd soon as the Perma SF build has been rumored to be hit by the nerf bat soon. Also which of them can farm the most places, and are not just limited to a small area to farm. Anyways before I asked too many dumb questions, thanks in advance to all that post helpful ideas.

Depends on what you want to farm. Monks are good for areas with very little healing and lots of fast attacking enemies. Lots of healing mobs however can be countered by Silver Armor capabilities of Eles and Perma silver form. I could break it all down for you but i stand at my first point. Depends on what you want to farm.

I really don't know what I really want to farm, what ever will make me some good money I guess. I just really do not know what there is to farm that will make my bank fill up and won't be too much of a hassle getting to, with whatever build I use. So suggestions on good farming spots would be cool I guess...

Cathedral of Flames is good for a 600/Smite on HM. For a 55 monk, Farahnur the First City is a good place for 55 farming along with the area outside of Bergen Hotsprings. UW ecto farming is popular right now for Perma SF sins. Ele's can farm the raptors outside of Rata Sum along with being good for farming Tombs of Primeval Kings with a Shadow form build.

I can't say about Monk or Ele, But Assasin is great.Rit is also very, very good for farming.In fact I really just use Rit (the most) and Assassin, and make enough gold to get what I need/want.Doesn't make me rich but can farm good areas, easily, with no worries at all.

Edit: And as far as I have seen, the build commonly used with the Rit is in no danger whatsoever of being nerfed anytime soon.I have heard the same as you about the Assassin, that it will be hit again soon though =/
