So the best solutions for me would be to release the cap of 150 points maximum per skills so that you can choose between having very strong skills or just having most of the skills.
I am not sure to be very clear but you should get my point !
The cap is needed. At high levels, many skills become ridiculous. For example, if you get Animal Magnetism to 500, you have a 100% chance of creatures respawning on your square, and you'd never need to walk around a realm to level up.
