didnt read your post, sorry, but i saw "spectator mode". have you tried having a 1v1, survival, 0 lives. 10 rounds. but with three players. 1 player dies(stays dead due to 0 lives) that player can watch the 1 v1 go down from his teammates 3rd person point of view or have a 4 v4 with mayhem but not allow supers the spectator goes in as a titan running bubble. the spectating titan can roam around the map and pop a bubble and be safe and not be confused for anther player. when my clan runs tourneys this is what we use to stream
