The most flavourful Rogue build?Follow

Yes, I read the FAQs. Are you going to read this now?

As I've heard from the FAQs and others that Combat Swords is the best levelling build and a great endgame build as well, I've considered going with that. But I also want a build that really speaks to the heart of what Rogues are.

Simply put, I wanna be a ninja--the good kind. Running around getting kills from the shadows, exploring through the darkness unhindered, being a sneaky *******; all that good stuff. If you can do that regardless of spec, alright then, but it seems like the Sub tree is the most ninja-like of all builds. As a bonus, it might help me cut my teeth, so to speak, on PvP (4 caster toons and I have yet to do a BG or Arena match).

Veteran rogues, what say you?
