Blizzard Rethinking Wild Pack Purchases
Ben Brode was out on reddit this evening and stated the Hearthstone team has been thinking about allowing pack purchases for Wild content due to their additional focus on the gamemode this year. Unfortunately, they aren't ready to say anything else right now.
The thread, "Why can't we buy Wild packs?" has been a question since Standard became a thing back in 2016. Unfortunately, nothing has been said about Adventure content but we can only hope that they too returns should packs for Goblins vs Gnomes and The Grand Tournament make a comeback to the shop.

We've been rethinking our stance on this with our additional focus on Wild this year. Will update you as we have more concrete information.
