Ultimate booya PvP I-Hurt-You build:
http://www.worldofwarcraft.com/info/cla ... 0000000000
This is my current build (how it will look at sixty anyway). It allows for survivability vs. multiple opponents, not to mention that you hit like a fucking truck. At level 46 I do 400-500 Sinister Strike crits and have eviscerated for over 800 damage.
Hey, how did I die in two hits build:
http://www.worldofwarcraft.com/info/cla ... 3003120301
This build creates combo points very fast, and is based around the ability to use those points to stun your opponent and continuously backstab them. Premeditation allows for various nasty high damage combos, i.e. ambush->vanish->ambush->kidney shot/premeditation->vanish->ambush, etc. usually by ambush #2 your opponent is way dead. This build kicks ass against anything but a warrior or another rogue, and there are still ways to win against them with this build.
Byebye's crazy experimental DOT build:
http://www.worldofwarcraft.com/info/cla ... 0030100010
This is the build I want to try at 60, it focuses on using Deadly Poison (the rogue's DOT poison) and garotte, hemorrhage and rupture to cause insane damage over time. Perfect for bypassing the armor on warriors. Just DOT them up, vanish, and wait for their health to deplete, then repeat and laugh as they run around helplessly until they die.
