Something I would really like to see in this version of WHFRP is the inclusion of evil/chaos careers and races. An Adventure pack would be perfect for this sort of thing. I've been playing WHFB for years now, started on a mixed chaos army when 6th ed beastmen were released. Now sadly that army must be redone, but that's not the point.
I also got into the MMO when it came out last august, dropping it around february, because the end game just isn't that fun. But I enjoyed playing my marauder a lot.
I would love to recreate that experience on the table top. I don't think I'm alone either, I would be willing to bet that there are a ton of players of both WHFB and the MMO who would love to continue playing Chaos/Greenskins/Darkelves/Ogres/Undead. So Fantasy Flight, please, please, please develope an evil career pack!

I would have loved too see most of the careers and maybe even new ones in the Coreset, but no. There so few "Normal" adventure careers in this products, that everyone has to waits its turn.
