From gameplay perspective, I hate that bows are so deadly. It is very much reminding me of Prophecy of Pendor, which was my favoutite mod in Warband, but elite archers were like machine gun wielding robots with laser sights. Archers in medieval inspired combat should shine in special circumstances like sieges or defending on hills, but otherwise should play supportive roles only. In the current state of game they are the king of battlefield.
This is a game, so I fi d ameplay balance much more important than realism, but I see huge issues from the perspective of realism as well. For sure you can have very strong, very accurate, and very quick bows, but these will be three different instruments, and the game currently combines this all. Horse archers were able to fire extremely quiclly, but their range was short and those were inefficient against armour. The famous longbow was good against armour, but the rate of fire was like 1 arrow per 10 seconds. But in the game you can shoot about three times quicker witht the strongest bows. The accuracy itself should very much depend on the distance as well. Realistically, I do no think archers could effectively fire aimed/direct shots over 30-40 meter, especially against moving targets or against targets with shields. On a longer range they were shooting indirectly, eg. a formation of archers targeted an area or a fomation of enemy.
