For anyone who didn't know, most Warriors in Heroes of the Storm had some form of baseline armor. I've no idea why, though I suspect it was to make each Warrior unique. That said, it wasn't clear who had what, and there was no hud indicator for this base armor. With that in mind, Blizzard have done away with the mechanic and instead given Warriors who had base armor, more health. How this will play out in a live environment, I'm not sure. Besides that, below the TL:DR for the Hero balance changes. Full notes here.
