Or how about the Mutants and Masterminds route where you have to pay for everything (ability scores, attack bonus, defense bonus, saves, skills and powers aka class features)?

All within a set power limit. The only neat thing about the M&M route is that you get to design how your powers will work through power levels, extras, flaws and power feats.
...you can make a new core class.
It is weird that the cleric, which is supposed to be the divine equivalent of the Wizard, tries not to look like a wizard.
