Hard to Distinguish the Knights of Immolation from regular Doom Knights

Pretty straightforward. The Knights of Immolation have some color differences, like the purple feathers on their shoulders. And their armor is a slightly different shade. But it is hard to tell them apart from the regular Doom Knights in regular gameplay. I often find myself mixing them up with the normal unit in gameplay, and in MP I could see an opponent not being able to tell the two apart.

Changing them to a silver color scheme or something else very different from the normal blue and gold would help a lot. And making their weapons actually flaming would help visualize their unit role at a glance without having to look at the item card for that detail. They are meant to have magical and flaming attacks, but the VFX are also a bit too subtle.
