So my human warrior has reached level 20. she's specced arms and has 4 signets for the 200 precision. I can hold my own pretty well now. I just met Queen Jennah and she asked me to report to 3 factions somewhere, who are all involved in fighting the Big Bad in some way, each with different style.
How does this work? Can I work for all 3 factions and get involved in all 3 at the same time? or are they mutually exclusive? And what's the difference between them?
