I suggested this before because I thought Balki's night claim meant he was protecting HR, and I wanted to keep them both alive. I figured we'd get a retraction and not have to kill either of them. If they weren't ever going to retract, then we would have had time to kill both of them.
Now, keeping the priest alive through the night ensures that we have a confirmed townie deciding between two people tomorrow, as opposed to three nonclears. If we're wrong today, anyone who wants to claim priest should do so just before EoN, telling us who they're protecting.
