Inferno faction discussion.

It's not the Cheshire Cat, why should it smile?

Here, demons are not just monsters; they represent chaos. They should have a half-mad grin, expressing their chaotic and insane nature. Moreover, they were quite humanoid (even if they resembled the D&D prototype), but now they look more like beasts. Previously, they resembled commanders of demon armies, but now they are just brute monsters, similar to Juggernauts.

The design is good.

It's bland and resembles a demonic version of the Rakshasa from the fifth game.

away from the cartoonish style of the fifth game.

This was actually a good idea because the cartoonish style fits well with the Heroes games (Heroes 2 is an example).
