Review Detail of Dogue in My Necromancer Class

Read until chapter 71. It' OK but the main character is not likeable for me. Level strenght is a mess, don't making sense. He get points leveling up and can spend those points in status but he don't spend a single point in physical status (Strength and Dexterity) but is faster and stronger just because he leveled up? How come if he didn't spend a single point in this and spend the points in MP and HP?
