I agree that the guide is pretty bad, but it's a good start to read up on stuff. Just ask yourself what kinda pvp you are looking for. Do you wanna run brainless into fights and soak damage(stamina gear is great!)? Are you looking for smaller fights(you can get away with more damage gear!)? Do you want to counter any classes?
Like what I did with my rogue, I believe that you win fights if you kill their healers. So I made a dagger rogue with as much AP as I can. For example the guide has the wrong dagger for getting as high crits as possible and he doesnt even mention any difference in gear between sword/dagger spec... My hp is really bad but I do insane damage and as a rogue you can easily chose which fights you want to enter and when you have cds up you can get away from bad engagements. This is my gear:

Anyways what I'm trying to say, just because people play with the same talents & gear it doesn't make it the best fit for you. Play some games before you enchant your gear and see what you want more of.
