Exactly, I would prefer to create my own companions and find them along the way. Solasta does exactly this granted you just all show up at once at the table in the inn. However Larian with its resources could write backstories for you and your manually made companions and probably make it GREAT. I am unlikely to play any of the Origin stories and that is fine NOBODY is going to make me and some folks will likely have a blast playing them, I just prefer to create my own so that I know I will have a Balanced party or an Un-Balanced party on purpose for role-playing.
