Hi, I'm new to Dark Heresy 2nd edition and have a question regarding experience gain:
Is experience pretty much given out arbitrarily and the rules for it intentionally ambiguous? My group plays in pretty random spurts (sometimes 2 hours, sometimes 8) and depending on different factors will get more done in a particular get together than on other occasions. So, how should I be handing out experience? A blanket "400 xp" every time we're together definitely doesn't seem right, but there aren't really good examples floating around...
Thanks.
