Soloing BRD (sorry if someone else has posted this, I have not seen it) Also, this is my first post, so it may be hard to read, just post questions and I will try and keep an eye on this to answer them.
The best run I have had I got the Fiery Enchant (35g), and the Ace of Elementals (300g+) for about 10 minutes time in the instance. Those prices are on my server.
My main is a rogue so this is written from a rogue point of view, but maybe you could do it with a druid?
Follow the steps to solo Plugger for the Barman Shanker. I am new to this site, but I sure it is posted somewhere here. If not, try
it is a decent but limited site (I plan on a couple contributions to them, but posting here first for you guys) 
The only variation on a Plugger (barman shanker) run is right after the Shadowforge lock. Go up the ramp and then go straight up the second ramp and cross the Ring of Law. You can pickpocket these guys for about 3-4s each if you feel like it. Free money. After crossing, go immediately to your right and see if Pyromancer Loregrain is there.
If he is, kill him. You need to kill him first, if you kill his adds and vanish, they spawn right back. I sap one, then ambush Pyromancer. I eviscerate immediately so that I don?t waste combo points. Then I blind the second add. It will depend on your set up, but I can blade flurry to do them both if I need to. I generally have to use evasion for this fight. I use Instant poison and Mind Numbing. I vanish after the boss and then the two adds are simple by themselves with a sap. I often need a single heal potion for this one.
He has been spawning pretty frequently for me (1 in 3?), and he drops the Fiery Enchant about 30% of the time. Thottbot probably says different, but those are my estimates based on my running it.
Go back through the Ring of Law and continue with the Plugger run. May as well kill him since he is easy, and then the door will open for you to get to Lord Incendius. I recommend killing the little gnomes in the room with the golems too (can't recall name of the room, manufactory?). The gnomes have been known to drop Black Diamonds.
After killing plugger, go out the door and drop down to Incendius? level. Avoid the elementals with him.
Poisons don?t work so I use Dense Sharpening stones. I have to drink a greater fire resist potion and put on all of my fire resist gear (I am at 127fr). I am far from ?epic?d out?. He kicks you, and the lava is death so line up well and go for it. I open with distract and ambush. I have to use my prep for this fight, and both evasions. I have not had to use thistle tea (I trashed the recipe, just got it back) but I am going to start using it. I also end up using my lifestone, whipper root tubers, and a heal potion. I recently added crystal restores, and night dragon?s breath so I am hoping it gets easier.
No lie?it is a tough fight. With the new items I added I think it will go easier but it can be done. The Ace is a pretty rare drop, but a damn nice prize
It is fun as hell and gives a nice feeling of accomplishment?and ?it?s a rogue thing? which rocks.
Variations?
A short cut to Incendius does not require you to open the shadowforge lock. You jump out the window right before it, drop to the walkway, and can go straight to him.
You can also solo the rock lord in the first area. Time the dogs as they are death to stealthers. He hasn?t dropped much worthwhile for me though
The bad news...
Getting out alive is a PAIN, so I usually hearth from there. The damn dogs are just a nightmare on the way out
