Welcome fellow Thief!
They have one of the most fun playstyles of any class in any MMO I've played. I change between Sword/Dagger and Sword/Pistol depending on my mood and what I'm fighting. Love dashing in and out and ruining someone's day. The only thing I can't seem to 1v1 consistently is Engineers who stand in one spot spamming bombs. It's easier to just run away and find an Ele to destroy..
