Wow, you really are clueless... Wizards of the Coast doesn't take balance changes lightly at all, in fact it takes them a very long time after extremely tiresome deliberations to ban/restrict cards in MTG. Blizzard didn't take this much time in the infancy days of Hearthstone, back when they nerfed Mages and Priests to hell, back when a lot of neutral cards got nerfed, back when UTH got nerfed than buffed, etc. Now Blizzard has actually learned a thing or 2 from Wizards of the Coast and are taking balancing a lot more seriously and cautiously.
