As for your raid experiences - it sounds like your host has a pretty bad connection. PvE uses a lot of peer to peer. It's the reason the Crota kneeling cheese used to work. If your host has a bad connection to the others, you will experience lag effects and even different game states between players, like you did.
Go to orbit, change the fireteam leader, and re-launch.
