I'm not sure if I like or hate more new skill system.
I like perks that let us change our gameplay slighty: (if nothing changed in alpha 17) we can achive temporary stun immunity by drinking alcohol or we can invest perks in passive stun immunity. This is interesting option that let us get something but we are not locked from anything by not taking it.
Same goes for "ninja movement" and "from the shadows" if we enjoy stealth it's nice option but not something mandatory, and many other perks.
What I don't like are perks that are not choice at all. We are either locked out from content by not taking them (vehicle crafting in my opinion should be book locked) or they are something that simply must be picked: block damage, stamina regeneration (anybody here enjoy waiting for your stamina to regenerate?), backpack place (should be achievable by crafting larger backpack in my opinion), more head dmg (it's really counterintuitive mechanic, i dont know any game that track where we hit and don't increase dmg when head is attacked, especially when our enemy is mammal), and unfortunately many more.
This is especially bad if such a perk is locked behind tree we are not interested at all making us spend 15 points in total just to get it.
