Halo 5 should have Co-op Checkpoints

For those of you who have played Halo 3 ODST with your friends you know what i mean. Checkpoints that would disturb your levels progress and you could start off at a certain point in a level that you and your friends were last on, in case someone lagged out or if someone had to leave.

In Halo 4 you progress isn’t disturbed if you have played with friends but many times there could be things that pop up that players have no control over and just have to deal with instead of going back to the last known location they were last at.

So Co-op Checkpoints Yay or Nay?
