PvE Thief
You could go S/D or S/P if you want to handle more than one at a time. With the S/D you’d still be able to Cloak and Dagger to stealth for when you need to get out. Infiltrators strike is very good as it will allow you to teleport to a mob but shadow step back if you need to get out.
Here’s a quick build I put together for S/D or S/P to give you an idea.

Thieves are viable for dungeons. Make sure to bring a SB for AOE and use your blinds.
Ferg Crossing
I prefer condition build for PVE and WWW (P/D and Bow). In the PVE I can handle most of champions (yes, with gold circle ones) solo with easy.
But this build killing packs of mobs longer, than direct DPS builds...
Seafarer’s Rest (EU): Liicher (Engi), Lii Cher (Warrior), Swf (Elem),
Licharr (Guard), Lich Eir (Ranger), Alt Fh (Thief). Lii Cherr (Mesm), S Wf (Necr)
I too would really recommend a Sword mainhand. It really is the best for leveling and doesn’t require a massive Initiative dump like Death Blossom spam.
Sword/Pistol really cannot be beat for soloing. All you need are auto-attacks(which cleave to hit up to 3 targets) and your number 5 skill to keep enemies perma-blinded.
Thanks for all the advice guys It’s helped me pick up my thief back up after leaving him for so long.
