That is one great feature they recently added was the ability to have players come back into the strike battles. So if people do bail out, try to stay alive and hide and maybe others will re-join.
Also in their defense, they might not have left on purpose. I was in a 2 hour strike battle hard as heck and no joke, got disconnected with the enemy at about 2 health. It was the most angry I have ever been at this game. I actually had to take a long break after that happened. 2 hours gone....
6 person raid
More bad news about the 6 person raid
1. No matchmaking which means you can ONLY play this with friends.

2. Must be at least level 22 or 23 to enter. Pretty sure it is minimum level 23.
In all honesty I hate to say this but I feel I am already starting to lose interest in this game. Was really hoping the 6 player raids would provide the necessary option to allow more than 3 friends to play together. But not having a matchmaking for the raid is just a terrible idea. Getting 6 friends online at the exact same time during the week is not that easy. Not that it matters since I am not even a high enough level to enter the raid. So really if you are not high enough level, you STILL cant do anything with more than 3 friends other than the crucible vs multiplayer.
