After what the community will agree was probably the stalest meta ever change is coming to Hearthstone.
Some changes are small upgrades, like allowing people to pick a random card back, others are huge like rotating Baku and Genn when the next expansion hits.
Those could be seen as normal changes for any game but Blizzard been having its share of questionable decisions and Hearthstone in particular is very slow to react to players complains.
Now, I won't go as far as say the next expansion will be the best thing ever, the new cards may create an even worse meta but at least the game showed some sign of life instead of looking the ship sinking and merrily saying everything is fine like they been doing.
