Second this. Not only is docks uncomplicated, but if you're feeling lazy you can skip every boss, but the last one.
If you do that the iron stars can't be used, but you can just stay to the left, and go behind the crates, and then behind the targets, and nothing will aggro you.
Walk by the 1st boss when he pats, the 2nd boss leashes if you go up the stairs, and like 15 feet to the left.
The 3rd boss you just stay to the left, and walk right by, and if you find out you can't legit kill Skulloc then all you have to do is survive until he cannon barrages.
At that point you can heal up behind the first barrels, and then plink him down from range. The one orc will just spin all around the ship until WW runs out at which point he won't move unless you dump your aggro somehow. You can even just plink that guy down from range, and then kill the 2nd orc, and you're free to drag the barrages out as long as you want.
SMBG's was the 2nd easiest for me. I found NZ to be easier than TG solo wise. NZ hits like a truck(150k on my DK), but stops to cast spells often enough that it doesn't matter that much, and I was able to just use AMS to run through the bones bad stuff without ever killing them.
Just don't get knocked off on the 3rd boss, and that's cake. Save CD's on it for when both the other worms pop up. Once they're dead the fight is mostly over unless you somehow stay out of melee range. In which case he will chain cast 100k damage nukes.
For the 2nd boss just don't fall asleep, or something. Or summon extra adds by not watching your step.
The first boss I just used asphyxiate, and then cast chains of ice on the sacrifice, and I got free dps time on the boss. Tank her at opposite ends of the sectioned off area, and it's cake. Just make sure you grab the lunary purity buff, or you get 1 shot. Other than that there's not much to it.
I'd rank Auch 3rd easiest after that.
