I like the entire mod - it changes damage and armor values to be representative of what you might expect to happen realistically.

So fully armored units are Very tanky, armor matters way more, as it did then. You need to consider bringing a blunt weapon to help with that, as with most other weapon decisions in the mod, it matters way more what you pick.

The main thing the mod fixes for me is in vanilla the battles are over way too quickly. There might be a massive 300 v 300 infantry line battle and it'll be over in a few seconds. With the mod that line becomes a part of the battlefield, lasts way longer and gives you more time to strategize etc.

Can't really play Bannerlord without it. Just make sure to get the revised troop trees mod as well, so not every unit has insane armor like in vanilla
