Right and exactly this is what I wanted to say account-based progression is ONLY for helping players to play more than one character!
(and for this reason, it is also not a contra argument against account based progression that it doesn't help new players)
But I brought up this point in this thread because I said it is a good FIRST STEP to help new players because it makes the second step MUCH easier and this is to give new players a certain amount of past lives and reaper experience for ALL the characters they might want to play.
I hope it helps you to understand, if not let me know and I may try it differently.
