My fourth and newest character, an assassin, has finally advanced far enough to serve a specific role in my roster: green farmer. Now I know my primary character can farm ectos, a few but decent greens, do amazing PvE, and so on, but I thought having this character do it would be a pleasant change.
Now, I didn't time this session, but I'm sure it took a long while. At least 2-3 hours. In that time span, I got 2 golds, a smattering of random items worth very little, and a green that I sold for 3k, (valued at 3-5.) My last attempt at getting a second green was the Mindclouder but after killing the boss at least 20 times, with no green, I got bored and decided to continue playing through NF with my new character.
So. My question is this:
Is green farming worth the time and effort? Should I bother using my assassin for this particular form of looting? Regardless, I'm sure I'll ocassionally use him for something.

Please share your thoughts and experiences. Thanks!
