From a PvE perspective, I am curious about your choice, Mr GrinsgarCZ, of investing in Strike From Shadows (+% From Stealth-Enhanced Skills Crit Chance) and Well-Practiced (reduction CD on Aim and Find-Footing). I learned from you how to optimize my skill rotation so to, in between Feint-Attacks, use all of my Crit Chain Skills before consuming it (Feint-Attack) with either of Surprise Strike or Cunning Attack. Reason being that all the while, I benefit from the "From Stealth" status (+30% dmg Bonus) for 15 seconds.
Cunning Attack, we can assume that is a sure Crit from the start, going on for 30 seconds. From lots of skill rotations, I believe that going Double-Edged Strike>Subtle Stab>Flashing Blades>Gambler's Advantage (insert here anything you may find useful before next CA or SS) takes perhaps 8~ seconds. At most. Considering Cunning Attack won't stack its bleed on crits, I don't feel that the +5% Crit Chance on it (and SS) is all that worth it. What truly is my main damage output at the moment is each and everyone of my Crit Chain Skills. I thought of dropping Gambler's Advantage due to it's low damage but then refrained since it "could" trigger the -5% Crit Def debuff.
Then, Find-Footing, I love that de-stun, but, knowing I can use it every 4 minutes instead of every 5.. Usually won't change my life much. I'd think it'd be certainly of use out in the Moors, perhaps, but, in PvE, I would love to learn why.
That being said, 2 days ago, reading you, others, testing around, I set-up my second Spec Tree as a different QK. Dropping Dust in the Eye, Startling Twist, etc. Quite close to what you have for QK PvE. But for now, just like you, I am missing the last Trait point from Big Battles, thus I kept Stun Dust in waiting. Still, should you want to take a look at how I'm set up now, I've put it up:

The purpose of my test was initially to understand what I'd lose from wearing the Earring for the BB set Positional Bonus. Mainly, for a loss of 1% Crit Magnitude, I lose about 3,8% dmg output, if NOT from behind. Which, obviously, should the info I've read about Positional Bonuses mechanics be accurate, will be coped for easily.
Once I get that last Trait Point, I have in mind of dropping Stun Dust for that last +1% Physical Damage. I still am in early testing of all that but truly feel I am hitting harder than I've ever hit before!
