how to fix these problems with rbm (realistic battle mod)

The mod destroys the economy. After a few fights, it's very easy to become a millionaire because of the price of loot. The game is just too easy.

Once you have a good level of two-handed skill, a two-handed axe, and heavy armor, the player is invincible. I don't find it realistic or fun that I can literally blast 100 guys single-handed.
