In Halo 3, the carbine was really rare in multiplayer, it wasn't because of a purposeful choice for balancing though. There was a technical limitation for Halo 3 on Xbox 350 that meant Bungie couldn't put every single weapon in the files for every map. Covenant weapons in particular didn't exist in the map files for several maps in the game so you couldn't forge them in. The only ones that were actually spawn able on every map were the Plasma Pistol, Needler, Spiker, Sword, Brute Shot, and Hammer. Even if you had a hacked game mode that enabled them as spawn weapons (since all weapons that couldn't spawn on certain maps weren't selectable in customs, including the Carbine), you would just spawn with no weapon instead.
MCC has this issue fixed, and all weapons are now available to forge onto every map. So I'd like to see 343 just go in and replace the BRs on some of the maps with Carbines. There are usually far, far more BRs on most maps than there need to be, especially when you take BR starts being the standard into account.
I personally just prefer the Carbine. In every Halo game I go out of my way to snag one instead of using the BR, but Halo 3 has so few Carbines in it I feel like I almost never get to use it, despite it being an equal-footing utility weapon that should be just as common as it.
I get that there are some Halo purists out there, that want the game "unchanged" but don't forget that over Halo 3's 3 year lifespan Bungie actually went in and tweaked weapon spawns on maps several times. Remember when Radar Jammers were a thing in MM? Or when Guardian had Maulers on it? A change as small as a couple of BRs replaced with Carbines isn't going to make all that big a difference. Think as small as one of the 4 BRs that spawn in each base on Valhalla, or one of the two BRs either on the middle of Narrows, or one of the two at each spawn. Far too many maps have 8+ BRs lying around without a single Carbine. And far too many maps only have the Plasma Pistol and Needler on them as Covenant choices (looking at you Last Resort).
Let the Elites have their guns.
