I know, stamina sorc has a lot of issues, and I don't want to talk about that here. There are enough threads about that.
EDIT: I put the details in "spoiler" sections to help alleviate the overwhelming wall of text.
What I need, is help improving my DPS against bosses on my stam sorc. Despite the drawbacks of stam sorc, I know I should be able to pull better numbers than I am. I am currently only able to pull between 9K and 12K DPS in boss fights, usually hanging out around 10K. I am convinced there is something wrong with either my build, or my skill. So please give any constructive advice that you have.
My build.

Primary Stats:
64 points in stamina
Max Health: 14774 unbuffed
Max Stamina: 22862 unbuffed (24690 unbuffed w/ bound armaments up, which I keep up all the time, obviously)
Stamina Recovery: 833 unbuffed (I never have problems with stamina)
Weapon damage w/ Bar#1 equipped: 3010 unbuffed. Bar #2: 2976 unbuffed
Weapon Crit w/ Bar#1 equipped: 38.3% unbuffed. Bar #2 equipped: 46.4%
Weapon Bar #1, This is my primary weapon bar for boss fights: Executioner, Wrecking Blow, Critical Surge, Thundering Presence, Bound Armaments, Flawless Dawnbreaker for Ultimate.
Weapon Bar#2, this is my AOE bar: Empowered Ward (this slot is pretty much just for the "Expert Mage Passive," I swap it out for Dark Deal if I feel that I need it), Steel Tornado, Blood Craze, Thundering Presence, Bound Armaments, Flawless Dawnbreaker Ultimate.
I use Distillate of Weapon crit during all fights to keep Major Savagery up and increase my stamina recovery, and I have all 3 points into Medicinal use.
I do well in AOE situations, always maintaining above 26K DPS, even against just 3-4 mobs. Basically I just keep up Critical surge and thundering presence, and spam Steel tornado and pop Flawless Dawnbreaker whenever it's up. I don't think I need work in this area.
In Single target/boss encounters, it is a different story. I once again keep critical surge and Thundering Presence up at all times, and I try to keep Blood Craze on the boss the whole time. Other than that, I mainly use Wrecking Blow with heavy attacks weaved in and pop Flawless Dawnbreaker whenever it's up. Despite this, I still only pull around 10K DPS in every boss encounter. What am I doing wrong?
