As it says, simply put. I think there should be a rejoin feature to games in halo 5 encase of disconnection, especially in arena; Meaning if the certain player leaves or is removed, only that certain player can rejoin. I have encountered times where My internet or the halo 5 servers have disconnected me or someone else during a game and because of this i miss out on a game or effects my stats and team. On top of this we may receive a punishment for leaving when it is not our fault.
The idea is similar to league of legends rejoin feature and means you cant play any game until you rejoin and the game is finished. Maybe the rejoin feature should be implemented only for arena as it is ranked and a serious game type; Unlike warzone where it is a more casual play and wont have a dramatic impact on the team if one or two people leave. (Other people can join in also anyway, so it works)
I only see more pros than cons to this idea and will make the games in the future more reliable.
