How about we read the articles we plan on sending? Does that sound good? Also might help to read what you’re replying to. I didn’t say that spike wasn’t ever used for deflecting sabre strikes. I said that they didn’t use it for that function in WW1, and your article agrees with me. Here’s another article

I have expressed that horns aren’t super common because they are heavy and in the way, which I still believe. If they’re too heavy they’re going to br horrible to wear. On top of that, they’re not only going to get in your way, but they’re going to be used against you. They can easily be hooked on to.

For samurai, the majority did not have anything on their helmets, unless they were high ranking. This changed later on where they started wearing frontal tatemono for recognition purposes. Side ones were rare, and most likely to be worn by high ranking individuals. They weren’t wearing giant horns for the common soldier. In fact when the frontal ornaments became more commonplace during the warring period, we can notice that the also became smaller. Most if not all of the samurai armor shown would have not been used in battle or would have belonged to officers. I’d like to learn more about their armor but unfortunately I can’t read or speak Japanese.

Also the random Mongolian doesn’t really show anything. You can google Mongolian armor and that’s literally like the only horned helmet you’ll see.

All that to say, if it’s in the way and heavy, it’s not going to be used for practical fighting. The larger it is, the more likely it has nothing to do with protection and more to do with status. I was also commenting more on the European inspired factions rather than the Asian ones, because I’d like to see armor additions for them rather than just barbarian stuff.
