The scalling of defensive skills is wrong.
On all other skills you have a normal scalling, for example : "one handed weapons" +4% damage, +2% accuracy each point.
For defensive skills like "vitality" it is 4% more health the first point and then +1% only by other points.
On "magical or physical armour" it is 7% on the first point and then +2% per other points.
So the only first point is interesting. Addmore "magical or physical armour" is not giving enough, I never could reach my health amount with armours.
Defensive skills should be reminded.
