IMO the primary stats as it stands are terrible from a design standpoint. They don't actually provide much of any choice or customization in their current state. What do I mean by this? Well, if I want to be a potent caster, I need int to be pumped every level. If I want to be a melee fighter, well then strength is my jam, and so on, and so on. With the way that your power gets stripped away from you if you stop putting points into a stat, you can really only afford to be flexible with 1 or 2 stat points ever few levels. Because of this, every choice the player makes isn't really a choice. There is the right way and every other way is the wrong way. As it stands the game would literally be better off if stats didn't exist and only skill specialization mattered. (think Elder Scrolls)
They really need to find a way to separate from skills being associated with stats if they was to keep the backwards scaling effects of the primary stats. (which I honestly hope they don't)
