What would it be? I would say the Plasma Launcher, or “Covenant Hydra” as this is already in the games files (I’m looking at you WZFF March on Stormbreak) and would not take much much more rendering to implement into the game.
I would like the spiker and most of the brute weapons to come back.
Halo: Reach DMR. Halo 2 SMG. Halo 2 Carbine. Brute weapons like the Spiker and Brute Shot.
Before anyone complains about the bloom on the Halo: Reach DMR, keep in mind that it would have the same characteristics of the Halo 5 DMR, but with a classic scope and more bullet magnetism. That’s basically what the Halo 2 Battle Rifle is compared the standard Battle Rifle in Halo 5. The Halo 2 SMG would be designed in the same way.
Flamethrower with a Flame Scorpion.
Halo ce shotgun
All the Brute weapons, Halo CE MA5B and halo 2 pistol(since it’s a weak weapon,it could be dual-wieldable)
Not exactly a “weapon” but I’d like Prophet of Regret’s chair/throne from Halo 2.

What would be the flames reach? Or would it launch fireballs instead of missiles?
I’d like the focus rifle (it’d be buffed of course) and the sticky detonator.

2 warthog-lengths of flame reach sounds reasonable.
I was thinking the secondary turret weapon could be an incendiary grenade launcher.

I like the turret incendiary grenade launcher. Would be fun being a passenger in that tank.
The only thing I wish for; Halo CE MA5B—it will make me happy 
spike grenades
Would love to toss one into that window on the side of the upper floor of garage and see how many people i can get xD
Id also love to see some odst variants of weapons, black magnum, odst style suppressed smg etc 
Halo 1-Reach Plasma Rifle! I know we have the Brute PR, (which seems silly to me, since we never even fight Brutes, and what makes even LESS sense is that ELITES are using BRUTE weapons!) but I would be overjoyed if 343 brought back that little gem.
The spike rifle, you know, that automatic brute weapon that could be dual wielded in Halo 3, but later buffed in Halo Reach? I loved using that thing.

Maybe it could be a normal scorpion but with a flamethrower on the side of the cannon like the chain gun on the side in Halo CE and Halo 2. Also it could have a black color scheme with flames allover it,truly an amazing vehicle by the sounds of it.
Still waiting, and probably will forever, on an MA37 skin for the assault rifle. Use the same damage output, sound, and accuracy, just with the MA37 aesthetics. I like the stripped-down visuals, and the shortened appearance.
Id want the classic weapons in halo 5 to be real classic weapons. They should have their original sound back there was no reason to change them. How come the H2BR and CE magnum get their original sounds? It’s not even the sound from the anniversary edition it is the sound from the original game, yet the SPNKr, H2 beam rifle, and the BPR get a completely different sound? That has just been -Yoink!- me off ever since they added them.
The Halo Reach AR.
Fire. I want fire.
