Oh, it seems I made an error in my previous comment. And no, I didn’t have any intention for them to be available in the Dark Age, I just happened to forget that there are only three phases for the Eagle line. I decided to edit out “Shock Infantry” from the unit line that I previously presented and where the [War Club Runner] will be the first phase once reaching the [Feudal Age].
I won’t deny on this. The reason as for why I included “War Club” and “Axe” in their names is because I remembered reading somewhere that both the Club and the Axe are closely related to each other, where the Axe was apparently developed from the Club by our prehistoric ancestors.
Maybe there could be an upgrade for the Incas that gives the [Slinger] the ability to throw burning projectiles just like the [Huaraca] from [Age of Empires 3], which will make them effective against buildings. Though, this upgrade won’t be that special if the [Staff Slinger] which is another unit concept that I came up with is going to get added to the game. Since some civilisations will be able to upgrade it to the [Fire Bomb Slinger] or [Fire Bomb Grenadier].
If the Aztecs were to be given the [Slinger] and an unique technology that affected it, then they could throw a projectile that causes a bleeding effect, because they did apparently use an alternative type of ammunition for their slings which were clay balls filled with either sharp obsidian flakes or pebbles.
If we were to direct our attention to the Chinese, I know that some people have suggested that the “Fire Lance” could be given to them as a unique unit. But how about also giving them the “Pao Che” (Catapult Cart) as well? The Pao Che was a Whirlwind Mangonel on wheels, it could replace the regular catapult line for them. It would be nice if another unique siege engine was added to the game, since there is so few of them.
I also remembered seeing a post from 2021 where a user made a mod where the [Scorpion] for the Chinese was replaced by a “Triple Ballista”.
