Seeing as it seems GW never made an official FAQ, nor uploaded an updated rule pack, looks like this is as good as it gets: https://boardgamegeek.com/thread/164416 ... -questions
Main one is that Bloodbringer (one of the extra characters I believe) has the wrong "fight zone" printed, it should be the 3 in it's front arc like Vexnar. (p.1)
Intention was that you can fight through obstructions (p.3) - means those fighters with longer reach get a little better!
