Here's an unpopular bit of news that Blizzard slipped out ahead of the weekend. If you're a Hearthstone player based in Europe, then you're about to get hit pretty hard by an increase to the real-money price of card packs. The costs of Adventure wings and Arena Tickets are also being raised.
While all European players will have to pay more for their shop items as of March 22nd - and regardless of whether you pay in Euros or a local currency - it's the UK that's getting hit the hardest. As an example, the two packs you buy today for £1.99 will very soon cost you £2.99. (Something something Brexit.)
Here's a breakdown of the new prices for the GBP and EURO currency regions, along with a comparison to their current costs. You can find details for local currencies over at this in-depth Reddit thread, where all the prices have been broken down by country.
