This has been one of my favorite threads... ever.

Soloing old multi-player content has always been a hobby of mine ever since my first character, a rogue, solo'd deadmines at lvl 32. No idea if that's even good for the time, way back in vanilla, but I was pretty proud of myself and then forever hooked on the concept as a way to spend my time (and in line with the thread, it was pretty good money back then too.)
That being said, I wanted to post up that I had killed Jin'do in ZG recently... but I see someone beat me to it and quite a while ago. I did it slightly different than shown in his video, but definitely on the same lines. I spec'd with a fairly standard pet survivability BM build that many use. I used health-heavy gear to boost the pets HP pool and healing regen from abilities. Strategy was to burn as hard as possible for the first few sec and let the pet, a dps spec'd cat with heart of the pheonix and lick your wounds take him down for the full duration of FD, using cower whenever it came off CD. If the pet would die before FD was done I'd pop up and allow myself to be MC'd. If the pet lasted the entire time I'd pop up during the last second or two with a kill shot. Pet dies, Jindo comes into melee (I did have the bugger reset on me once as he was evading during my shots and just happened to reset inbetween when the next set would have come out, but only happened once). Drop some traps, pop heart of phoenix, lick your wounds, use melee CD's and FD before another MC trap comes out letting the kitty finish off the remaining %.
I have never had an MC totem allow me to heal at all during that fight no matter what I tried. If anyone had that happen can you isolate what made that work? The above strategy worked and seems repeatable... but takes damn near forever and is pretty boring. At least as boring as viper stinging the bat boss for what seems like forever before you bring her below 50% health. I just wanted to get him down once (and probably again to make sure it wasn't a fluke) to ensure I could do it.
The rest of ZG is pretty easy... and still my favorite instance for making gold. Even selling bijous dirt cheap (in comparison to the other few on the AH at any given time), they are still well worth the time all on their own at 15g each. They almost always sell at that price point, where anything higher and it becomes pretty spotty. Still, clearing all the trash and bosses takes about 3 hours, and I average somewhere around 50 bijous, which comes out to about 750g alone, plus vendor greys, cloth, DE mats, and other AH items (mojo still sells, albiet spottily). The raptor pet sold for 500g the other day and went pretty quick, so should I get another I think I'll price it higher. The poly:turtle books don't seem to sell very well, so I've been giving them away to mage friends.
MC is on farm and I have at least 16 more full runs to get the rep. Once I taught myself all the fights (with help from the geniuses (no sarcasm implied)), I use the croc for almost all the fights, save garr and golemagg (turtle) and Rag (wolf or cat). I've also found that if my pet is on passive for the sons of flame phase that sometimes they will actually despawn when I FD. Anyone else had that happen? I think the circumstances are 1) stop dps 2 sec before submerge and put pet on passive. 2) FD the second you see a son of flame appear and target you. There will usually be 1-4 left, but they are much easier to handle than the full group... but I still haven't had it happen with 100% accuracy.
I've done AQ20, except buru and ayamiss, including Ossi without doing the crystals. I started working on Buru, but I ended up running out of patience that night... but I know he's doable.

Much less motivated to run all the way out there now, even with the engineer's teleport to tanaris now that CC rep is exalted. I'll get him before cata.
So the real challenge is Karazhan. I was able to down Moroes a few months back, which was pretty cool, but I had a very hard time repeating it. That day I got Oz for opera and couldn't even get close, even after reading and watching a vid of it being done. Tips?
Killing Moroes a second time 2 weeks ago on a Mon, I was pretty happy. Ended up with Wolf for Opera. 6-7 tries later he died to some decent kiting, which is the main requirement to solo as a hunter. If you don't set up your position for the next kite phase, you'll get hammered, and is well more important than any amount of dps. Moving on, Nightbane was pretty easy and straightforward. Stay out of the fire, don't get tailwhipped, make sure the pet gets the skelletons instead of you. Consistently I had one skelly at ~20% life as Nightbane landed, which was not at all a problem. Curator... was a problem. Hateful bolts and damage from the few orbs I couldn't kill fast enough damaged me too much to be able to recover from, and while getting close I never got him into an Evocation. Anyone done this fight successfully? I saw a vid of it being done, but that hunter didn't take nearly the damage, so perhaps some level of AR gear?
Sadly when I went back to Kara the next day (due to raid reset that day) I couldn't get Moroes even close again with the same enemy character composition. I really wish I could do that fight consistently.
I think the next endeavor will be some Wrath 5 mans. I'm curious to know what their worth is monetarily... and of course the challenge of doing them solo.
I know there is a 500+/hp5 trinket from ony10, which I have yet to see drop (likely to little guild interested and having dislike for raid pugs). Is there another 500+/hp5 trinket, and if so where does it come from? atm I only have to 100+/hp5 trinket from the ony head turnin.
Any comments and tips will be greatly appreciated, thanks.
