wish list for halo 4 - some new features, if not too late

If not too late, would be nice to see features bellow on Hall4 or …5.
I would like to see Spartan and Elite:

  • be able to lay down, at least with precision weapons, as real snipper.

  • be able to kick stuffs, push things on top of enemies so they die crushed.

  • be able to see valid counters for sprees, maybe when press start.

  • waypoint on xbox showing same information that waypoing on web, medals.

  • add your ideas to the list. I couldn’t find one.
