Is it worth keeping the class-card packs from the book of... Adventures for the upcoming mini set?

Hi guys, 

U lately started playing the solo adventures and was wondering, if it would be worth keeping the packs.

The mini-expansion was (and probably will be) 2000 gold so it is best to buy it for gold, but sure, if you have complete collection and do not plan to buy the miniexp for gold or real money, save them until there is an expansion (big or mini) with cards you miss

So the cards in the packs are always standard format? 

Or standard from the time, i received them?

They are from Standard at the time you open them (I used rogue, priest and paladin packs at the start of Barrens to get the new cards, for example).

My own plan with them is to hold them until the next full expansion arrives, and use them effectively as packs from that expansion. I have more than enough surplus gold from the Rewards Track that it is most efficient for me to use that for the mini-expansion.

Note I did use packs I had saved up for the DMF mini-expansion to great success, so it is perfectly valid to use the class packs for that, but it would only be reliable if you already have the full Barrens set.

Thanks guys. :)
