Based on what I've managed to scrounge up on the wiki, I've come up with this highly mobile, hard to kill build. It could quite as well be called the Bastard build because it will have many players yelling bastard and other obscene things at you as you continually harass and evade people. http://www.gw2tools.com/skills#t;fak...fUa;cYba;bjfZY
The Build's main point is control and mobility with the Sword/Pistol set while having the pistol/dagger to play keep away when needed. This build is full of shadowsteps and dodges galore, just enough to make people through their keyboards in frustration of how slippery you are at getting away. The Sword/Pistol combo is the bread and butter as it provides the control and mobility all in one weapon set. Lots of pvpers will tell you that the kill doesn't always come in the form of burst, and control arguably is the most important factor when it comes to downing someone. My choice of utilities were picked because of the mindset behind the build:
Withdraw - Mostly everyone goes for Hide in Shadows and it is indeed powerful, but I choose this heal because of its extremely short CD(shortest in the game IIRC), built-in evasive mechanic because when you heal, you're typically in danger of some sort and having an escape that grants you a fraction of invulnerability is very handy, and again reinforces mobility on the most mobile profession in the game. What I think is MOST important is the lack of a casting animation. You simply roll back like you are dodging and gain health. Not to mention I don't want to be like every other Thief out there.
Shadow Refuge- for support for allies and another stealth, which would in turn grant you a boost to Ini regen.
Infiltrator's Signet- This is somewhat an enigma because we don't know exactly how much initiative regen the signet gives. I'm going off the modest and reasonable expectation that it gives 10%. Initiative gains are 1 iniative per 1.66sec or .60241 ini per Second(pips for here on out)...
so with the signet you get .662651 pips[.60241+10%=.662651] Now add the trait Quick Recovery 2ini per 10sec [.2 pips] and you have .862651 pips. Now our initial rate of 1 initiative/1.66sec is now 1 initiative/1.15922sec
Spider Venom - This one is mainly used to net a kill on someone. When someone gets low, they'll use a heal. Seeing as how in GW2 you don't have to watch out for healers laying off in the back to pop their guys back up to 100%, the only reliable healing is through self heals. Ideally you would like to put this on as they are getting low, and with the Sword/Pistol just repeatedly spam skill-3 (Pistol Whip, 1sec stun). My traits play into this because of Combined Tactics(Dual Skills return initiative when completed). *OR*...
Roll for Initiative - This could be subbed in place of the venom if you further want to go salmon on your pursuers and slip away.
Basilisk's Venom(Elite) - While looking around the other night, I fell upon something that I thought was absolute pure WIN for the Thief, and frankly if it's still in the game come next BWE, I'm going to use it to cause thousands of players to cry in frustration of how amazing I am... Oh, I'm not talking about this skill itself. Oh no. What I'm talking about is this little gem right here **Rune of Lyssa**http://wiki.guildwars2.com/wiki/Rune.
Lots of talk about trait builds and weapons, but not so much about runes. Just scroll down on that page to find that set. That entire rune set would shore up some crit for my build, give a boon whenever I use my low CD heal, and most importantly every 36sec(Remember, Quick Venoms lowers my Basilisk to 36sec CD) I would have a very reliable and powerful tool on such a short CD to cleanse my conditions and give me all boons. The Thief's biggest weakness comes from their inability to shed conditions. They only have 1 utility to do so, and then a trait that removes 1 condition every 3 sec in stealth. Hardly ideal and one that the devs should look into IMO.

10pts in Deadly Arts - Center around the build using steal as it's primary trump card and get the Quick Venoms.
0pts in Critical Strikes - IMO weakest pvp trait line by far
20pts in Shadow Arts - More Defense, More Healing, Longer Stealth, Stealing Stealths you AND gives you initiative.
20pts in Acrobatics - Remember I said this is a highly mobile build for a highly mobile class right? Shore up some of that low HP and get some higher Initiative gains from Combined Tactics and Quick Recovery. Not to mention swiftness on evade and gaining back endurance whenever you dodge.
20pts in Trickery - Ahh, My favorite line by far... Lower the absurd CD on Steal(45sec! with 20% would make it 36sec), leave behind caltrops on dodge(more synergy yet again with acrobatics line and overall theme of build), and give a powerful buff to yourself and allies whenever you pull out the ace up your sleeve: Steal.
Sorry for the lengthy post, but I've been eyeing this build for a while now and I constantly make tweaks to it. Of course, this could be all for naught when the BWE comes and all the skills/traits are all tweaked and nothing is remotely similar to what I've researched. But for all intents and purposes, I will be using this extensively in the BWE if it is still intact and I will be recording videos throughout the weekend to showcase some things off. I've scoured forums and videos, and I have yet to see anything closely resembling this build. If I've overlooked a forum or video and all this is just pure coincidence, please direct me to said video/forum so I may look incredibly stupid to everyone on these forums, much more so than I already do. Thank you for your time.
