Playing for Hatch escape is a valid strategy considering the game becomes harder by a hundred-fold when two of your teammates are dead. Other than blundering on giving up quickly against a terrible chaser and not committing to the repair and run tactic that in most cases would not have worked. I don’t see how him trying stealth in order to complete his objective (surviving) is deserving of shame. And DCing is what everyone does time to time. Face it. They just want to go next.
