I haven't got that far, but I'm not sure I would be upset by the shift. If your are playing it like role playing your are leveling your character fitting to what you are doing at the time, not with some end battle of the game in mind. The progression you make fits what you doing, and then presumably something unusual happens that introduces this over element which turns everything upside down.
I can see that, but the problem is that it removes complexity instead of adding complexity.
Imagine if, partway through the game, all of your characters got a talent which made all abilities scale off of Intelligence, instead of Strength or Dex.
Not only would all the points you spent on Dex and Str have been wasted, but it would reduce the variation in your characters. There would be no reason to build a strong guy, or a quick guy. You might as well just make 4 smart guys. Which is less interesting than making a varied party, with characters who have their own unique skills.
