I think the packs are way too pricey, especially since they all feel watered down/lite versions of packs from previous games. Sure they have a few new things, but it's focused solely on that "new mechanic/gameplay" that it seems to skimp out on CAS/BB items, skills and such.
I'd like to see the prices of all packs drop by half; Expansion packs are now $20 USD, Game packs are $10 USD, and Stuff packs are $5 USD. They'd probably sell more since the prices are cheaper, they might even be able to make the same amount of money as they do now, so we the consumer see it as a better deal and are more likely to buy it immediately. But I'm no business genius and that's simply what I think.
