Guild Wars 2

so… i’m new to thief…

anyone can help me with what is best to run in pve?
i’m thinking about either s/d or d/d…
what should i use for levelling? and on lvl 80?

and the most important question…. what traits should i use?
i’m not really good with trait distribution… ^^""

thanks for the help

For leveling, I imagine D/D or S/P would be pretty good. I don’t really remember what I used.
In terms of PvE later on, there are really 3 main weapon combos and 2 MAIN builds.

Weapons
D/D: Your main weapon set for bosses.
S/P: Your main weapon set for trash mobs.
SB: Your utility weapon for blast finishers (might/stealth) and mobility.

Builds:

5/6/0/3/0: Good for fractals and beginners.

6/6/0/0/2: Good for all other dungeons.

MAIN is emphasized highly in terms of thief builds as a lot of times a good thief finds themselves swapping traits and utilities a lot. This knowledge comes from watching videos and personal experience.

Guide:
The following is a well written thief guide with a lot of useful information written by members of popular PvE speed run record guilds.
