As they stand they make no sense at all, and there are too many of them.
Go Shadow of the Demon Lord and very few would have a stat above 15. Then make each tier of attribute more comic book - Athletic, Olympic, Peak, Superhuman etc.
Also each class has no access to magic unless picked as a feat, e.g. cantrips, chi, pact, training etc.
Edit: this would allow a berserker to gain Warp Spasms like in Slaine
If you want classes to remain, there should only be three core classes, Magic-User, Warrior and Rogue.
then perhaps you would multiclass those 3 classes ??
