The annoying thing really about the attribute system in this game and, in say D&D, is that there are almost always inflection points; for example, you only need X amount of Memory for Act 1 and need Y amount of Wit to ensure that with +3 Leadership you will always go before most of the mobs. Then the rest goes into Strength/Int/Finesse (your primary attr).
Because of Larian's decision, and other designers, attaching non-uniform bonuses to attributes then factoring in the other systems you end up having those inflection points. There is always a danger that adding more things to attributes ends up creating a more toxic atmosphere while doing the opposite will lead to more stability but at the cost of diversity and meaningfulness (why even have attributes at a certain point). For example, removing the relationship between attributes and accuracy would allow for more potent hybrid builds in terms of damage (and also it would make finesse stronger since you would have less sources of accuracy).
I would be happy if they took another look over accuracy and gave some D&D 4e-esque abilities that cross scaled between attributes/weapons and diversified the 'skill' trees to include both magic/physical damage abilities.
