I think what would be really helpful to solve this is an "Idle" toggle in battle option that when turned on their turns are sent to the party leader like when disconnecting for example. This keeps tabs on things (party leader is responsible now) and only works in a party but gives options to trapped parties like Senna mentioned above. This of course should have exclusions like does not work with mercs or any sort of afk grinding option. All in all is strongly toward player to player emergencies.
