Return of Reckoning

Yo, I just learned about this server and am excited to play. Having only played Warhammer Online for a bit after it's initial release, I don't know anything about the game other than I had a blast playing it. I was Chaos, a Marauder mostly. Have y'all got any tips on starting out? What's an easy class to get to learn the game, what are the do's and don'ts, etc.
