Hum, sorry, but it has nothing to do with it. It's like saying that in a game you have 5 different powers, only one is useful, and "it's good, this game works!". No, it does not work.
On 5 magical skills, there's one that taps on the physical armor, cool. The others remain unnecessary in the case presented by Veligan. Moreover, and if I do not want to develop Necromancy? I have to do it nevertheless mandatory, because the game system completely breaks the diversity of the gameplay that existed in the 1st?
At the same time, in their system, you just need to put a point to have all the skills. Because yes, to better use a weapon, camouflage or magic, you just need memory ...
