Think of it like making a super-hero movie. Would the majority of people rather go see..
A) A super-hero movie told from the perspective of a street-cop who would one day become a great super-hero but they have to sit through two hours of non-stop flashback then a cliff hanger ending before the movie where he actually gets his powers is released a year later.
B) A movie about a cop who gets super-powers at the start of the film and gets to meet the interesting characters right away when he starts to hero about with his new interesting powers?
I think most people would choose B).
If you trying to let people skip the boring parts of being a new character, that's a great goal. I wholeheartedly approve of this idea because we should always strive to tell the most interesting parts of our stories. A multi-tiered, confusing system with weird confusing names seems a poor method to do it instead of just allotting everyone an XP bonus from the get go to flesh out their abilities more. It would let people skip to the fun parts where there characters aren't as useless as a level 1 D&D character.
