After reading this thread I decided to go play w/ sol ro with druid / warrior*. DB of 550 max hit of 1600 avg hit on stonewalled warrior was 600 dps (unslowed) on stonewalled warrior was 550, estimated 300-400k hp, bash that lands every other round that stuns you. For those who go to duo him etc, keep in mind he has single target ramp - his ramp is rather nasty (2 hits + kick/bash possible per round.) Ramp rounds were spaced 2-4 seconds, so it's rather nasty - interupted druid casts like crazy.
*warrior buffed to 16.7k hp (oak + ornate bp + FoE3), 3k ac, has max avoid / shielding, imp dodge / parry 3
The guards have 100k hp a piece, db of 300 max hit of 1300 - avg hit on warrior was 500. There are 3 pairs of them, and they have a huge aggro range. I was in his chamber for 45-60 minutes and didn't have them repop. Killing each guard pair took ~12k mana from druid - I had willsapper proc`d on all them (fu willsapper taking 2 minutes to proc on sol ro.)
As far as shaman soloing him... If you don't have 17k+ hp, 60+% focis, near max ds all around, max shielding and stun resist, etc etc - I wouldn't even bother trying him. You would need to be able to survive a harsh round + stun + DD, so you will need a lot of hp to back you up.
It took me over an hour to get to him, albeit druid medding between the pairs was a lot of it. Took about 15 minutes to clear to chamber, killing 6x guards and medding for sol took 45-60 minutes. If you are seriously thinking about doing this, you will need to get fresh raid buffs and clear to sol w/ multiple chars so you're able to engage w/ max hp.
