I'm pretty sure PE divides skill points, not attribute points. The problem I have with this is that it forces you to have a combat-and-social build, not allowing you(r character) to focus on one or the other. I'd argue against it until I'm blue in the face (and in fact did exactly that). In D:OS's case, the way it is now, an increase in a primary stat (in other words (and better terminology): an attribute) causes an auto-increase in what is effectively a skill. Sure, your proposed system seems nice enough and a social skill tree merely influenced by whatever "stats" (and traits) seem appropriate would be great, but I'm fairly okay with the way it is now.
You're talking about a concept I've improved and revised in a later post from myself here. So it doesn't make much sense to discuss this one I think.....
