Hearthstone patch 5.2.2 is now live! It contains a series of hotfixes for both the regular client and mobile applications. More interesting than that however, is some sort of reference to free packs!

So far all we've managed to find is a single string: "set_rotation_2016_free_packs" has now been activated. Seems like Blizzard is planning some sort of free pack promotion as part of the upcoming adventure. This is very similar to what we experienced with the Whispers of the Old Gods promotion where special quests granted you ten total packs. In the strings those were defined as "set_rotation_2016_questline."
