Guild Wars 2

Hey forums,
After much theory-crafting and testing, I have finally made a thief build that can last in the current meta state. I will explain the main changes and reasoning behind certain trait/sigil/weapon choices and what makes this thief build currently the most fluent build in HoT.

TRAIT LINES
The trait lines are an obvious question for most people when viewing the spec. As I was testing this build with friends, I was often asked why take Shadow Arts (SA) traitline over Deadly Arts (DA), which is the current thief meta. While DA offers so so so much (mug, panic strike, and improv/executioner), SA is a much better choice while running Dare Devil (DD). The reason being this: DD + SA essentially gives you infinite mugs (stealth regen and pulmonary strike), while giving you so much sustain. Though, you do lose the weakness on poison. Fortunately, you can easily swap out DD first trait from the 7% increased damage to the weakness every 10seconds for 5seconds based on team comps you go against. With SA you also conserve a lot more initiative and dodges (because steals give you stealth, which is essential in almost any situation). A conservative thief is a good thief. Finally, while improv is beyond good, you are never guaranteed a good proc from it. That being said, relying on improv is never a viable option.
WEAPONS
D/P – Obvious choice for headshot (pulmonary strike synergy) and stealth.
Shortbow – Rotations/survivability/godtier
*Nothing else really works well with this, so D/P SB will always be your weapon set.
SIGILS AND RUNES
D/P – air/energy
SB – Generosity/energy
Daredevil Runes – Constant crits
*Double energy for the extra DD rune crits. You can swap out D/P energy for almost blood/fire/rage.
This build is far superior to the current interrupt thief, so good luck!
