In reality, if you are looking straight at the Templar when he first spawns, the area to the right of him is a perfectly fine and safe place. The shield carrier can destroy harpies in one melee. There's also a giant pillar to hide behind to avoid Templar blasts. You really don't even need to kill the oracles if your whole team stays close so they can be cleansed. While I understand your opinion, is it THAT big of a deal?
