So, I decided to go in and try solo some SoO trash out of boredom, and I ended up making roughly 50k an hour.
Basically, clearing the first 4 packs (The two on the side and the two packs of guys siphoning the bubble person) was netting me a fair amount of epics, and being grouped with an enchanter to zone into the instance allows me to disenchant each of those epics into 2x spirits (~9k on frostmourne alliance).
I ended up bringing some friends in to clear it out faster (and kill the 3 giant adds before Immerseus) and they just paid me 9k per epic they needed, so same profit.
Armory link in sig, wouldn't recommend trying this without a decent ilvl.
Any questions n shit, post em.
