From the UNSC video, it’s pretty clear. I can already tell but not having to even yet see the Covenant Weaponry and Promethean Weaponry videos (if 343 is going to release them)
Dual-Wielded Needlers - You can easily shred players the moment they come around the corner as you could in Halo 2.
Dual-Wielded Magnums - With the RoF being fast being similar to Reach’s imo, you could put somedown fast at close range. Dual-Wielded Magnums could overpower both the DMR and the BR.
Dual-Wielded Storm Rifles - Imagine Dual-Wieldabe Assault Rifles…yeah you get the idea…
Dual-Wielded SAWs - Do I even need to explain this? You’d shred Vehicles even before the player had not even a slight chance to hit the gas. Not to mention the advantage given to people who guard the base or spawnkill. You’d get an Unfrig in like 5 minutes.
Or it could be the exact opposite and all the effected weapons that are meant for dual-wielding is complete crap, and not worth picking up on the map. 
Yeah, unlike the half-a-weapon effect from H3.
It could be properly implemented if dual wielding caused a sizeable drop in accuracy and a slowed reload.
Lol…dual wielding SAWs…the epicness. End of Halo 6,chief dual wielding SAW’s holding of the flood and rampant prometheans and a precursor.
Dumbed Down version of OP’s post:
Difficulties with Balancing prevent Dual Wielding.
I agree 100% OP.
