Why does this even happen can't they just have it so when someone leaves they just leave no "Connecting to host" or "Starting game" because this is getting bad. One time this happened and it skipped an entire round and the enemy team was able to score while our team was waiting. And also sometimes it takes so long so me and my friends are forced to dashboard and get back on. Bungie needs to get rid of this or adopt MW2's system where if the Connection host leaves it only takes 10 seconds until everyone can play again instead of 10 minutes in Halo.
I've never seen it where an enemy team can score during this period, that may be because of your connection. Whenever I get a connecting to host error, everyone is frozen, and the weapons on the map just get respawned. But the amount and length of some of these can be quite annoying.
I wish halo had a search connection preference like set it to like search for Australian games and this would never happen. Like halo has search for good connection games and three quarters of the games you get are laggy games anyway. I have had the same problem as you in some games the whole game resets
Because if you could do search for games of a certain country, people would choose some country as a boosting country.
