What i do is use 2 daggers and specc into condition damage and spam death blossom. damage is premium and it has plenty of survivability since death blossom includes evade. then i go dual pistols for tank duty for the blinding powder or what ever its called (nr5 attack) you can keep up a blind for the whole fight if you do it smooth.
Edit: as for slot skills i used to only use signets but now that i know the class well i just play around with what ever i feel like to come up with new methods. but using only signets i feel is a good idea if you want less to think about.
