I find it rather weak that only one player can have improved defence or any of the other non-basic cards for that matter. If you have two warriors only one person can have the cards. It may be good for balance etc. but if you have more than one slayer in your group, then only one of them can have the special slayer attacks. That's pretty weak. They should at least release a package where you can buy extra cards.
Also the extra dice package is lame... you just get a few extra dice, not even an entire package.... you have to buy quite a few of them if you just want the GM and players to each have their own set.
