PvE condition build help...
First of all I would try getting different gear. The spec itself is for Venoms/Stealth, not for either condition damage/ critcannon. Some Power/Percision/Condition gear would set you up nicely for basically spamming CLoak and dagger and pumping out tons of bleeds with the pistol and applying the poison venom, while a critcannon build can venom-share vulnerability.
The big problem is right now S/P DOMINATES PvE, the super long evasion on pistolwhip and ovveral effectivness of blinding powder makes surviving a breeze, I literally went full damage gear, full damage runes, the only defensive things I had was the offhand pistol and my utility skills catered to the specific Dungeon (shadowstep and shadowall in CM ect…)
TL;DR
Focus on doing damage and causing vulnerability. Either AoE with a sword Power Percision and crit (Better for PvE) or if you refuse to get a 2nd set of gear go Mainhand pistol offhand dagger.

P.S.
picking the right utility skills is what a thief is all about, abuse shadowstep to early turn off traps, Shadow refuge is one of the best rezzing abilities in the game with its 15 seconds of stealth it also lets you run past 500 mobs and stealth your entire team. Smokescreen is an instant-win button in many pulls. Calitropes for kiteing (think the first boss in AC explo where you have to protect the NPC) Just stay away from signets, they wont bring as much to the table as other well played utility skills.
