I managed to get 1k by just the gold itself, by the end I got about 1.5k, I had to get a new ID kit and Exp. Salvage kit so I made about 1k in an hour but if I hadn't have had I'd have made still about 1.5k.
I went later in the night with Corwin in a higher level area, which was a bit of a pain just the two of us, but we were making 100gold in about a minute rather than ten in the other area. We made about 1.5k from gold alone and by the end I had about 2k from selling off items and such, which we got less of but more gold so it sort of evened out. It was a little more annoying due to how difficult it was for the two of us, a W/E and a E/Mo kinda have a problem there. Hard to keep ontop of healing.
We went back to where I had farmed earlier and between the two of us we made 1k in gold and then plus items we sold off. We got a couple runes, even a major, and since it was Frost Gate, we ended up getting about... 38 stone summit badges between the two of us. I had 21, he had 17.
It went by quickly, and though its not the best mission to farm, it's still good enough. By the end of the night from about 5pm til 2am I made over 5k, because i had only about 9.2k in my vault, now I have over 15k. So in about eight hours I made 5k, not much but could have been better if we didn't fool around a bit on the second Frost Gate run.
So, down to the actual questions...
What, in your opinion, is a good farming run? How much gold per person and how many unidentified items? What I mean is BEFORE you sell them off what is a good amount of gold to walk away with?
I had more fun in the more difficult place, more higher level things to sell, worth more, but it was easier in Frost Gate.
How much gold per hour makes a good farming mission to you? Like how much gold you get in an hour that makes a good run otherwise it isn't? If that makes sense.
I had loads of fun last night, I wasn't in a mood to do anything serious so I farmed while Corwin worked on a new char for a bit, I had a blast compared to usual, running and doing quests that were backlogged or a new character of mine.
So, can you guys help me out a bit with some suggestions? I feel it was really successful, I more enjoy it for the fun than the profit but some tips would be nice too.

PS: I don't really have a farming build just went with what I thought would be good with my E/Mo. Can list my skills I took out with me if need be on the solo run if that would help, or any suggestions? I've got all my points into fire, energy storage and healing. 12, 10, 11 respectively in the order I put above, Fire and Energy Storage have mods to up them by one, or fire by two.
