Very cool list, I'll keep this in mind! Interestingly, the Banished Hunters are called Hunter Captains, and I'm surprised I didn't make the connection as they actually first appeared in Halo Wars 2: Operation Spearbreaker under the Hunter Hero, Colony.Chieftains more than make up for how easily the majority of brutes go down to any precision weapon. You shoot off their helmet, to get another helmet, then you can headshot them. The hammer chieftains are legit scary, I swear it was the final boss, not Harbinger. Due to my pure unshackled autism, I've been making an AI tier list lol. I'd say for the enemies you will run into in terms of difficulty to kill them (on the difficulties I played being Heroic and Legendary), and their ability to kill you, imo it goes:
S+: Banished Hunters
S: Gold Elites, Brute Chieftain Ultras, Classic Hunters
A+: Ultra Elites, Spec Ops Elites, Brute Chieftain, Sniper Jackals (Legendary), Rocket Skimmers (don't see a lot of them)
A: Red Elites, Brute Captain Ultra, Gold Brute Berserker, Sniper Jackal (Heroic)
A-: Elite Minor, Brute Captain, all Brute Stalkers, standard Brute Berserker
B+: Gold and Purple Brute Minors (gold is TECHNICALLY BETTER)
B: Blue Brute Minor, Grunt Ultra, Red Jackal, Skirmisher, Commando and Shock Rifle Skimmer, Sentinel Major and shock rifle Sentinel
B-: Blue and Purple Jackal Minors (purple is technically better), Sentinel Minor
C: every other Grunt rank
Basically I think that the Banished Hunters are god awful and that fight with the two of them in that small room in the Silent Auditorium on Legendary was horrible. Not insurmountable obviously, but I died a lot, didn't cheese it, but on my successful run I really thought multiple times that I got very lucky. Anything in the S tier can kill you in a 1v1 if you aren't on your game. A+ are very dangerous when put with a lot of other units to distract you, and can quickly end you. Same with A tier, but less so, and you will almost always beat them in a 1v1. The B tiers aren't bad by themselves, but could potentially kill you in number. And grunts are grunts. Sniper Jackals and Rocket Skimmers are only as high as they are due to how quickly they can kill you, although if you know where they are, no big deal.
The Spec Ops Elites are apparently Elite Zealots, actually. The Gold Elites are apparently Generals. There's another kind too, Gold and Red: Elite Warlord.
Many of the names have changed with the Banished. Elite Minors, for example, are called Elite Mercenaries (which makes sense given that's what they are).
