Hearthpwn

Thanks a lot for the info guys. So, every big patch we get new chapters. That is good to know. I'll save gold for the next mini expansion then if it is so soon

I came back to Hearthstone after a long break. I am not sure how often these mercenary stories come out, but I enjoy the packs i get. Do we know when the next one comes out? It appears to me that its kind of random. I mean, it doesn't seem to have a specific date each month (correct me if I am wrong).
