Here's what I propose, 343i has made a little description of every armor set that is in the game. So why not use those variants as an addition to Warzone? Think about it... the possibilities are now endless. Say you wanted to work on quick scoping or nadeshots, some of those armors have descriptions like that. So I suggest that the armor set you choose before the game, depends on what extra abilities you can use as an advantage over the other team. Nothing OP of course but just enough to give your Spartan an edge. I think those with all the armor sets should get rewarded for all their progress made in the game.
