The civilization in question has inferior troops such as weak archers and castles, as well as skirmishers due to the lack of bracer technology.
Additionally, their knights’ +2 bonus against archers is not effective, and they lack siege engineers.
Although their war elephants are strong, they are difficult to obtain.
They may need to capture the castle early in the game to advance, but there are other civilizations that are better in this aspect.
They are better in team games and hybrid maps but lack depth and versatility.
To improve their performance, they could be given bracer technology, goldless or cheaper arbalests without bracer, or siege engineers to enhance their bombard cannons’ viability.
A passive bonus to improve their archers or strengths in other areas would also help.
