I hope constitution bonus is retroactive. I HATE when you have a stat that yields less when you spec later into it. I feel forced to spec into constitution early, just to get the most out of it. Ot just make level independent, and 1 constitution = flat hp increase.

Secondly, I hope you have plenty of spells in the game that are not that much focused on scaling with int. I like to play Warrior + XYZ (magic specification), e.g. Buffs, Telekinesis, Summon beasts and other utility. I get that int = more damage, but that shouldn't mean that you're opted out of magic just because it isn't your primary stat, at least not for all spells.

Lastly, I don't feel Perception at all. It seems very weak of a talent, except for the hit chance. It's kinda a moot point, because I don't really like to waste points into it, but never hitting almost forces me to do so. A slight increase to critical chance / critical dodge on top seems like a good idea. That's why I always like when you have "secondary overlap increases" on other stats. E.G. 1 point of Strength = +10 melee damage, 1 point Dexterity = +2 melee damage. Same the other way around for ranged weapons. (it makes sense, as your little 4 page document has showed. More strenght = faster / better draw. More dex = better handling of the melee weapon etc).
So having Percetion +10 accuracy, and strenght +1 for melee, dextery +1 (or something) for ranged would be beneficial to my gameplan.

Armor:
Not receiving ANY damage seems odd. It should at least deal 1 damage imo. When someone hits me with a sword, it hurs, even if it's just a tiny bit.
