Well I made it down to my store and picked up the last chapter pack of the Skaven Cycle and then the first two of the Enemy Cycle(and a bunch of AgoT and D&D heroscape stuff, my poor wallet) and I am very impressed by the cards in the Enemy packs as well as the theme of each pack having two rivals in them a bit more as per the name on each pack, very well done. Good job Fantasy Flight as always.
The story bit in each was a nice touch as well.
I found the story to be pretty basic stuff, it didn't really do anything to add to the value of buying an expansion pack, imho. I could very much do without it.
Fair enough, I'm sure they can get better, just a nice touch. Its the thought that counts. =)
Frankly I think the story bits are quite poor and too short but at least they present the Hero units as actual characters which is always nice (it's something Magic does with great success) - it makes you care much more about the flavour and fluff. As for the new cards - they're simply great! There's an idea behind each card I've seen from the Enemy cycle so far which can't be said for the Corruption cycle cards. Overall great stuff!! Can't wait till the second deluxe expansion!!
There are some great cards in the enemy cycle and I am excited about the forthcoming battlepacks.
IMHO the storys are adding flavour and life to the game, but could be written in a more interesting style (I only read the german versions).

Daw....you guys are gona hurt Mr.Godwin's feelwings.
Seriously though I sent him an email thanking him for taking the time to write the stories, and possibly just because he included Slaanesh in the story... 
. Hoping to get Prince of Pleasure in this Cycle.
i thought it was pretty awesome to include the short prose in the packs 
nice bonus compared to previous cycle
it is what it should be imo...don't want too much in them lest it increases the prices!
I seen only the first part yet, but it's ok. At least the hero cards are not "random unit with Unique/Hero limitation" anymore, but have some character.
