Instruction: we stand on Payload with the Reinhardt shield up. The enemy Reinhardt is facing Payload and is using Earthshatter. In some places, the shield does not block Earthshatter.
Pretty sure it’s because the bottom of the shield doesn’t touch the ground under the payload and they have it so aslong as there ground is clear below the payload, anything above it is also hit.
I did watch the whole video but as you gave only your perspective I gave my thought on that. But I’m glad you seem like a nice, reasonable person to talk to and not a “insert insult of choice here”.
