No, you're looking at the problem from completely wrong perspective. Rewarding people for playing right class is totally fucked up way to design game. All it creates is unhappy customers when you realize 80 levels later that you picked wrong class and will forever be second class dps.
All specs should be roughtly equal in complexity and damage. All specs should pull some crappy 1k dps if you spam one button, and when you mash all 10 buttons in right order regardless of spec all should still do the equal maximum dps.
