You know, you are just proving his point. A casual gamer will hardly check the forum for the best builds, he wants to skill his way.
You do not need to check forums for good builds, it was just a friendly suggestion to help him because he appears to be struggling. The information is all there ingame and it is just a matter of taking the time to read it and figure it out.
Also, I am not sure I have ever played an RPG that rewards "skilling your own way" over a well-thought out and synergised build. Given that you can respec everything after Act I, it really could not get any easier.
