Although this is true, I do agree that they look pretty terrible. They are easily the worst looking faction. I hate to speak without having all the facts on the table, but the Sturgians are clearly the faction that Taleworld either had the least amount of time put into it, or simply didn't know what to do with.
Sturgia needs more lamellar, more gilded helmets, more chain, in general more "eastern"-style equipment. And also more colours than just blue, which just invokes "Nord" too much, when they're indeed Kievan Rus inspired. Reds, browns and greens like the Sturgian riders in the concept art during loading screens would complement their colour scheme nicely.
Yes, but that's besides the point you're making, which is that the helmet you're refering to looks bad, which I agree with.
