Guild Wars 2

I’m thinking about playing again after a very long break but I’m finding alot of information is outdated. Stickies that are 2 years old are not uncommon on the forums and it’s difficult to sift the facts from the fiction in the normal posts.
Is there somewhere that offers and up to date comprehansive guide on the basics of the classes? I’ve logged in to find that everything is very different with little explanation of how the new systems work. I logged into my character and I have no clue what stats I should be aiming for or what choices I should be making with my skillsets.

Any help is appreciated

You could try the Wiki or Dulfy.net
