Well, while not exactly "solo" farming, yesterday (which happened to be Pierce's second birthday) I did a bunch of SS/LB farming in HM out of Remains of Sahala . Surprisingly, with a 6 character crew I was able to make 25 platinum over the course of the afternoon and evening, as well as getting a few perfect items/mods that I didn't sell to the merchant (20/20 sundering bow string, a few decent inscriptions, a few regular tomes, and 1 elite tome).
While not necessarily the fastest way to farm cash, and I don't need the SS/LB points on Pierce (since he already has the max SS/LB titles) it was a good way to make money, as well as up Pierce's Treasure Hunter and Wisdom titles (both of which are now at Level 3). And, while I wasn't really doing this to gain XP, as a consequence of this farming Pierce achieved 4 million XP.
Of course, the best reason for doing SS/LB farming recently is because I have been spending alot of time logging in from my hotel room, and the internet connectivity is inconsistent. In true solo farming a pause in the internet connectivity would kill you in a heartbeat - while in the SS/LB runs the heros/hench do most of the work, and with 3000 health (when inside a wurm) you don't have to worry about instant death.
But of course, once I get back to a stable high speed internet connection, I will need to give some of the other solo farming locations some more thought. I appreciate the links to the farming threads (especially the Monking Around thread) as that gave me some good insight. One of the other good solo farm threads I have seen for HM farming is
330hp Rt/Mo Vengeful Spirit Bonder - HM Farming! (good thread, although the guy has a big ego). While my Rit presenlty doesn't have VwK (I haven't gotten an elite Rit rune yet, and he hasn't made it to the location to cap the spell - yet), the bigger problem is that he has only been to maybe 5% of the GW globe - so I will need to get Rift to zones where he can farm.
But, as mentioned by Dean, perhaps the best way would be having all my characters do a run through Elona for the Treasure Chests. Of course, the precursor would be getting the balance of my characters through the NF missions (Pierce has done them all, but the rest of my characters are at various early stages of NF mission progression. Since you don't need to be solo to do this,
if anyone else wants to join me for advancing characters through NF and then subsequently doing chest runs, please let me know. (NOTE: According to Rod, it is better to do the Treasure Chests in reverse order for better loot, so I plan on doing this in 2 stages). :D
