I made a post about this way back when on the Bungie forums, now I guess I’ll bring my idea here.
Invasion really needs to be something other than Red vs Blue. One of the biggest purposes of Invasion is to have a more canonically relevant gametype other than “some Spartans are fighting each other because they have a different flamboyant color”. Honestly, I think we can all tell between an Elite and a Spartan on the battlefield. The way it was set up in the beta was much better than how it is now, but it could still be better. Hear me out:
For the most canonically relevant (and cool, IMO) setup, Spartan characters could use their own custom colors, and Elites would have colors according to their armor rank (ex. Minors would be blue, Rangers would be white, Generals would be gold, Zealots and Field Marshalls would be that purplish-maroon color, etc.)
This is a minor change that would really make Invasion so much more enjoyable and give it that sense of purpose that it used to have in the beta. Please, let’s get this catch on and hopefully it will make its way into the title update!
