I think the Original Poster is asking for a branch of 2 jobs. He wants to make a tree, with different traits he's asking for PLD to not be as common as Gld to give Gld some new aspects and not only Gld but all other Classes. It's like trying to spec out your character how you want it with 2 choices you can either go dark side or the light side not star wars reference fyi.
I don't mind the idea at all.
