Question about Rogue DPS

[shams]

Hey all,

Been thinking about creating a rogue to level up when I feel like grouping and I was wondering what about them contributes most to their DPS. Is it backstab or their weapons on auto attack? From casually looking around when I'm in EC I've noticed that a lot of their weapons have great ratios. Also, if I did go Rogue (haha)... what order should I prioritize starting stats and then stats on gear as well?

Thanks!
