I don't agree "Wits are King".
I've never really bothered with it (except drinking a Wits potion to get the Braccus Pantaloons).
Who cares about initiative? Either you are first or you aren't. So either you put enough points into Wits or you didn't. Assuming you don't know in advance what initiative every other person has you may as well either pump everything into it (and be weak) or forget about it and go last. There is no point putting half your points into Wits on the off chance.
Even when I've ended up with lots of initiative I'll often skip a turn anyway to let the others go first.
Your suggestion that CON is underpowered is certainly true - I think everyone agrees with that. I do anyway.
The rest of your points I just don't understand. Finesse should give piercing damage irrespective of weapon? Hmmm. Unarmed? With a lump of wood?
Intelligence should do something not aligned to spells? Like what? Be better at lockpicking?
If I understood I'd probably disagree but as it is I just don't get it so perhaps it is all a good idea. Whatever it is
