Blizzard has confirmed that the Dragonflight nerf to Binding Shot to make it break with damage is intentional.
The change to Binding Shot’s root to break from damage is intentional, and there’s some history with this ability. As many probably remember, it was briefly changed to break from damage in Shadowlands, but that change was reverted.The launch of an expansion is a good time to change things where necessary, as it’s almost a reboot for many parts of the game.
