I know, really simplistic version, but the point remains that if there is a logical narrative explanation to get the group back together during an action scene, then figure it out from there.
If that was the circumstances in my game,, and if it were that quick and easy to regroup, I'd feel fully justified in putting the Doom Die back in the pool. But like you said, simplistic.
One thing that could be useful is to have the players
come up with a reason why they cannot regroup at this time. Also, if you've split the group and have a player left thumb twiddling for an extended period, it might be an idea to temporarily cede limited
control of one of the bad guys over to him/her. I say limited as the Watcher should have final say over whether any actions are "in character" for the NPC. You don't the player intentionally going easy or overcompensating and going beyond what the NPC would normally do.
Thankfully, I've not had to spend any dice to split the party since my player's seem to have never heard of, or are actively seeking to refute, the old RPG adage of "Never Split The Party".
