And it is selfish to expect people who don't like origins to just put up with a subpar plot and less options.
The op is advocating for removing already existing content in one area because they feel that content in another related area is sub-par in comparison. it feels petty and punitive. I am saying keep that content, do not remove it. I find it hard to see what is selfish about not wanting roleplaying things removed from the game that already exist and money has already been spent on. This is not a zero sum thing: removing origins will not magically make custom "better", though for some reason people seem to think that is how it would work. As verte says, don't remove the origins, bring the custom up to standard and use the level of detail put into the origins as a benchmark which you can then point to and say: we want this level of effort for custom pcs too.
