Since the marketing of D4 is “return to darkness”, armor should work more akin to previous armor design. HEre is how a good armor looks on D1 :

How Amazon characters looks with many armor on D2

Now look to D3. Armor looks like a Carnival suit. 50kg pauldrons, 50 kg open helm and bikini armor.

As you can see, there are fantasy elements in all examples, but the unique that is ludicrous is D3. And most fantasy elements has a interesting lore explanation, templars have a weird religion on G1 and the armor is not only for combat. Is ceremonial. Also, the game happens in a penal colony and articulations are not something easy to do.
“But mages uses robes in most fantasy settings, armor makes more difficulty to cast spells in a lot of games”
Sure, but even robes, could be more akin to ancient religious figures and folklore, example? Firemage robes on G2.

Mages would probably use something akin to Gambeson.
This talking visual wise. Mechanic wise, i don’t wanna see your can’s DNA being 100% tied to the gear that you are wearing. Gear offering minor bonuses is FINE but as Kim said, gear will matters but not be everything on sources of power.
That said, armor should offer protection. Nobody believes that a naked char and a guy with the best armor in the game should have the same defense. But how the defense should work? In video games, you have basically 3 main systems.
- Armor class with chance of deflecting blows(eg - Diablo 1/2, most D&D adaptations with excpection of SCL)
- Armor reducing in a flat amount(EG - Most Gothic series)
- Armor reducing in percentage(eg - Skyrim, diablo 3)
- Others(like morrowind’s armor system)
PS : This is a simplification. On Dark Souls 2 for eg, physical defense reduces in flat amount but the defense vs dark/fire/lightning is by percentage.
What i don’t like in armor reducing in percentages is that it kinda trivializes the weaponry. For example, a sword vs a warhammer. You can make the sword faster but the warhammer draining more stamina, slower and dealing more damage, with flat amount and AC, you can have a weapon better vs poor armored enemies and another better vs heavily armored enemies. This applies to any setting, even futuristic ones. On FNV, a SMG will outDPS a rifle VS unarmored enemies but deal almost to no damage compared to a .308/.50 BMG armor piercing vs heavily armored enemies. It is amazing. Collaborate to build and weapons being more situational instead of having a "best build"
The flat amount can also be used as “immunity”, eg, if an playing gothic 1, and only know fire bolt(30 damage), any enemy with at least 30 fire resist is immune to my fire bolt. Same for melee weapons. You will not gonna pick a shortbow and damage Gomez from his thick armor… Once you find better spells/weaponry, then enemies that you could only hit on critical, now you can hit. It serves as a reward system too and make little incremental damage gain much more important.
Eg - Enemy with 30 ARMOR and you with 35 damage. You will deal just 5 damage. With a better weaponry or better stats, if you now have 40 damage, you doubled your damage vs that enemy. If armor absorbs 30% vs any weapon, the damage gain will not be significant and also will be the same in all encounters, when with the flat amount, the 5 damage gain can double the damage in one situation and be a minor gain in another(eg - enemy with 5 armor), making each encounter and each mob more unique
So, IMO Diablo 4 should armor be back to AC of D1/Defense of D2 or move to a flat amount.
