Was just thinking why not bring back every single map ever made since CE days. Obviously skip repeats like Lockout and Blackout but any map that ever existed even those PC exclusive ones should be brought into Halo4.
It would add more variety in playlists and people who hate any new maps can always stick to their personal favorite forever.
Or let new generations appreciate maps that were awesome in their time and still hold their own in this day.
I say every map ever cause this way people don't get mad cause this map got in and this one didn't. All in, all in rotation for a specific playlist, if you don't like any of the new maps then you're in luck as all of the old ones are still there.
