Classic Playlists in Arena?

So, now that we have the custom game options, the weapons, vehicles and the super in-depth forge mode why has 343 not given us permanent classic-style 4v4 arena and BTB playlists with Halo CE, 2 and 3 styled gameplay with no sprinting, spartan abilities, classic settings with faster movement, shield/health behavior, and remade maps?

At this point in Halo 5’s lifespan, there’s so many options and not having it all in matchmaking is a detriment to the game’s community. I know I’d at least occasionally play these modes if they were implemented and for those who were less than satisfied with Halo 5’s gameplay and yearn for classic Halo gameplay with a new coat of paint would definitely be in heaven with this.

As much as I love the classic playlist, adding another playlist would just stretch the community thinner than it already is. I would be alright with them replacing one of them (Fiesta or Griffball). As for BTB Classic, I don’t think it’s necessary. Just have one classic playlist and leave it at that.
