343 industries needs to go back to the way halo character ID use to be. They should add a ranking system just like halo reach. At least add the playable elites to the new halo game halo infinite, I think a lot of elite fans would appreciate that update. The pelican, phantom as well as the spirit and condor, things like that should be a playable vehicle. The most requested vehicle in halo fans have been asking for is the Falcon, so if 343 can add these things in that would be great.
There are a few threads about things to add to H5 (like vehicles) you can use for that. There is also a dedicated thread for the discussion of playable elites linked below.
