Legend
Most definitely. We had this to an extent already with 4e roles. For example, the Paladin was a Defender Primary and Leader Secondary.
I think (gut feeling) this is where a lot of the tension exists in terms of design and balance.
We intuitively know that these roles exist, but we (the community) cannot agree or determine if we want it codified and stack ranked, as it then creates a perception of handcuffing how one plays the character.
