I have been playing Reinhardt since the preorder. I have been through all the ranks several times and have expansive time with the character across many years. The reason rein is valuable in his role is because of his ability to to take damage. There is no reason to limit his health even by small margins. 550 is a solid number even with his shield health nerf and lowering his ability to stay on the fight will only lower is apt to be a tank. Rein players feel this change no matter how small. Please consider this.
