The difference is that one point in the ability is all you need for any first tier skills, you don't need two points to learn first tier skills.
This will allow you to build a deck of low-tier utility skills, and encourage you to specialize into certain areas with higher tier requirements.
So you mean DOS1 skill point distribution ?
That has pretty the same result as current system.
Compare one lvl 5 skill to 5 new schools with lvl one.
This effect made any hero to take a point which ever school was even a bit usefull. Becouse it is hell lot of better.
e.g. every build in this system has at least 30% same skills. e.g. everyone is doing everything, again.
