I feel a nice touch to the game would be adding that every single time you hit 10 on a stat you would unlock an ability and example is
Strength: you have to make a 2 handed sword 1 handed also being able to pick up conscious people from the arms, legs as well as neck
Speed: if holding a none special weapon you can press the ability button to get a speed boost for a short period
Telekinesis: picking people up
Just things like this would make people thing about character builds combos and overall make the game more interesting
