Also: The fact that players will still gain more skil points at higher levels does not help?
Well, one of the posts above shows some calculations about skill points.
Say you get 5 points at the start of the game, 1 point until level 6, 2 until level 11(?) and 3 till 20(?). So it's 50 points total and with that you won't even be able to get all single tree abilities to top tier.
Maybe specializing is not such a bad idea if you take companions who can complement protagonists abilities, however, since they are not obligatory the game should be enjoyable and completely beatable without them, therefore I think there should be enough points to cover a decent variety of abilities.
