Level Up (A5E) One thing A5E could take from OneD&D: Power Sources and Class Groups

[lichmaster]

Both Class Roles and Power sources are from 4e, and were much better implemented, for the record. The design of them for D&Done is laughably shallow. But crappy implementations of great 4e design is kind of o5e's entire MO. I'd definitely suggest checking it out.

Class Groups date back to 2e (at least)
