Just to clarify, are you saying this having actually done it, or are you speaking hypothetically?It's more disruptive to my immersion. If I have to step out to roll a die and then step back in, very little disruption has happened. If I have to step out to quickly formulate a dream, very little disruption has happened. If I'm stepping completely out of the timeline and going back to play something in some other time, then come back and have what I just played impact what is currently going on, it's a significant disruption to my immersion in the character.
