Increasing Skill Level cap from 20 to 25 - An Idea

Actually this thread along with this quote sparked a thought in me, nothing i care to test myself.
But has anyone made up a count of different varieties you can make with the 20 points? And are those varieties “good”.
This kind of count-up would make sense to do, to see if a something see to expensive to reach or to cheap to reach.
While i don’t think we should be looking at buffing at this stage of development, i think balancing should definitely be investigated and this count could perhaps uncover some imbalances in the game.
