Level 28 strike Playlist that is only bosses. Make it a daily. Players port in to the boss fight of each strike. Each victory gives an engram. Rush ends once all bosses have been cycled so you fight each one only once. Completion yields a random legendary engram. Maybe make it so you can only enter once a day. And people who die stay dead. Make it hard. (I get the feeling people will make warlocks for this). Bump if you're high level and want more shit to do.
