What I would want is a slower gain, but a bigger cap. The high potential gains is fine, but low/average should be able to squeeze out a little bit more. I think it should be rare for a player to gain over 10 points in 1 season even with a high WE and high potential. If he had room for 40+ gains, he would need a redshirt season or luck from off season gains and a lot of points in it his whole career to hit the cap. Now you have more options of what to work on, but obviously some won't be able to max most out because you won't have enough points to spread into so much cores. You'd have the choice of say reb/lp/per on a guard, or go for the traditional per/bh/passing with minor improvements into def and possible a point or 2 into reb.
With all high/average in those areas it will look better then it really is, but at best he gains like 25-50 in 3 different areas if you only focuses on them. This will bring back the old style of more options, but will allow for us to continue to practice on all/most areas until he graduates w/o gaining to much.
