I agree that having the opportunity to flesh out custome characters is important. The problem is that it seems they are putting most of their effort on origins, not so much on custom. They might not even decided on how to flesh them out. How to offer an story arc that is only for custom but that doesn't overshadow the origins (in interviews they always talk about how we "need" to play origins to "understand" how special the character is and how that comes into the plot). So if they offer the same to custom characters, people might not be as interested in planing as an origin. I think that they would improve custom only when they finish the origins.
I also like custom characters better, but right now they feel too generic.
