This is a beta discussion, and should information change then obviously a smart person is aware that opinions and statements will change accordingly. So for now, we can be safe in the knowledge there are no more spells.
Comparing skills to treasure would indicate that the weapon you have will affect the actions you can take within combat, this is seriously unlikely. If you have fireball, you can do something different than if you have fire elemental. However if you have a sword with +1 single handed, it will not function differently to a sword with 8% crit and 15% stun. Sure, you may act differently, but you cannot perform a different action by lieu of the stunsword.
By placing an emphasis on skills as treasure you are indicating you would prefer the randomness, but that only leads to games where you never find the spells you need for your character to play as your character - imagine finding 8 geomancer skillbooks when you intended on using a pyro/aero caster with a ranger? By allowing too much RNG to creep into gameplay you actually reduce the likelihood to enjoy the game.
To take it further, how much randomness do you want in your gameplay Erra? Are you going to random your starting characters? How you spend your points? Which option you take in game? Or are you going to do what you want and spend things exactly how you wish to? Because I'm not clear on just how you feel random skillbooks are enjoyable over, say, ending up with your starting characters putting 2 into pickpocket and 1 into 3 different weapon focuses with a 10 perception?
But obviously the above point is only relative once you understand skills are not treasure, which they're not.
