Assuming it's a linear scale that starts at zero.
Before you criticize the absurdity of something, perhaps consider that might be your assumptions that are making it absurd.
Maybe the lowest possible strength score is -100. The, yours increases by perhaps 30% during the game (again, assuming a linear scale).
The problem is, the game does nothing to suggest it isn't a linear scale. The game does nothing to suggest strength can go below 0. Sure, you can attempt to find loopholes and explanations for it, but ulitmately there's no evidence for them in the game. It is absurd.
Not that I fundamentally have a problem with it being absurd. It's a gameplay mechanic. It's there to provide an interesting experience and to allow the player to feel increasingly powerful over the course of the game. It's an abstraction to add to playability. Which is fine. Changing over to stat customisation primarily on equipment is much the same, a gameplay decision. Neither have any real basis in anything other than gamplay.
And as such, when people complain about the change because they don't like the gameplay implications, I don't mind - personally, I don't really see the difference in terms of gameplay, but that's just me (I'm not saying I'm in favour of this change - in truth, I don't really see the pont of it, but the actual impact is likely to be negilgable so I don't really object). But when they point out a gameplay abstraction is ridiculous from lore or RP reasons while simultaneously defending an equally ridiculous abstraction, I just laugh.
It's much like the healing threads. Apparently DA:O having lore breaking healing is fine, but DA:I being possibly lore breaking in different way is not.
