Ok I make it simple.
Why even show us the numerical values of our attributes. In the past i needed to know these to disrtibute the free points. And now ?
What do I need that in that information for?
Damage calculations often feature the notion of diminishing returns, so knowing how much a stat increases in comparison to the total prior to whatever you're equipping can still be useful there.
For example, if I have 50 STR and 21 CON, and I have two swords, one that increases STR by 10, another that increases CON by 7. The STR sword is clearly better, right?
Well....not necessarily. Seen as an opportunity cost, I'm losing out on boosting my CON by a higher percentage increase, even though the actual number is less. So it may be that the CON sword allows me to try some things the STR sword can't. I don't know if such thinking will actually apply in Inquisition as I don't know the damage formulas, but even without the exact formulas it can still be useful to see a numerical representation of your strong and weak areas, and by how much you can seek to either reinforce those strengths or cover those weaknesses.
