Welcome I would like to begin the game as the Barbarian and I don't know which build to choose?. Whether Ravage or Wolfpack.

Just play what you like :)

Over the last 4years i played many games, with and without taking a look at guides.
I found out...that it kills a huge part of the fun playing a build of some guy instead of my char and as long you're not aiming for E-Sport of Hardcore-MP...fun is the only reason to play ;)
