This suggestion seems like the type that may have been suggested before, but I don't think that if it has been suggested before, it was suggested recently.
Intro: My suggestion is about the addition of statues into the mod. These statues would be akin to the troll statues and wargskin rugs that already exist in the mod.
Why statues?: I personally long for some architectural flourishes in my bases. While there are carved blocks that exist already, I don't feel that suit the needs of builders like me.
The Idea: Each faction has their own type of statue, craftable on their crafting table. There would be four parts needed to create the statue (similar to the mounted troll totem pieces). The first part would be crafted like a helmet, but using your preferred faction's carved brick. The second piece would be crafted like a chestplate with carved brick, the third piece like a pair of leggings using carved brick, and the fourth piece crafted using carved brick in the shape of a pair of boots. Once these parts have been crafted, they all must be placed on the faction's crafting table (shapeless crafting). This results in the creation of the faction's normal statue. This statue is in the shape of the warrior of that faction. However, it just stands there without any weapon. To customize your statue, you can use different colored eyes to trim your statue. If a player wishes to give their statue a weapon, then they craft a weapon on their faction's crafting table using carved brick instead of ingots.
Appearance and purpose: Each faction's statue is shaped like their warrior. This means that the statues still stand about 2-3 blocks high, depending on race. The coloring of the statue would depend on the faction of the player who made it. For example, a High Elven statue would be light grey, whereas a Mordor statue would be black. These statues could also be used as a replacement for beacons. Upon placing a statue on a block of Gold or Mithril (a block of Naurite or Gulduril for evil players), all friendly units within the radius of effect gets a small increase in attack damage and speed. This simulates how people can feel a strong sense of protection for their home land. It would also make server wars more interesting, as one side could use different statues as a rallying point for their armies. Once major characters and fixed structures like Minas Tirith are added, statues that depict famous characters such as Gil Gallad, Isildur, and Sauron (for the evil players) could also be added.
If you have anything to add to this suggestion, just let me know. Constructive criticism is appreciated.
