Well if I could choose how customization works, I would allow to choose almost everything in a single faction, and to dress however you want. "To know what you're facing" yeah we know what we're facing, a dude with a sword and a shield or a dude with a two handed weapon, what else am I supposed to know lmfao, the only thinking I do when facing someone in Bannerlord is: block, and attack. Yeah that's it. I guess how fast could I run from them does have a weight, but even with that in mind the choices are too limiting still.
TL;DR: Give even more choices for customization, make it cheaper, let us not wear helmets.
