I think the secret to Guild Wars 2 is to play one of the generic "do everything awesome" classes like Warrior or Elementalist. Then once you have that down, you can play some of the crappy classes, like Engineer, Necro, or Ranger... and just play a Warrior or Elementalist forever.
What.
I mean I realize all classes can do everything but they each have a different way of doing it. I'm sure we'll see constant fluxes of nerfs/buffs especially GW1 skills changed pretty rapidly at the childhood state of the game
And to zlatko, I'm sure you can't get a key if you don't "pre-purchase"
