Way Point system in halo 4

So the other day my friend and I realized that one thing the HUD could use is a waypoint system. That way you can set a waypoint on a location for everyone to see. for instance if your trying to point at something its would be easier to set a waypoint than to shoot at it and waste ammo. thoughts? suggestions?

Yes, agreed. Just like Gears 3, press down on the left stick to incidate what you’re looking at. But it should be disabled for multiplayer for sure though.

Good idea.
hopefully idiotic people won’t abuse it like in Portal 2 when they get mad, though.
