I understand what you’re saying fragfest and actually feel the same. We used and still use archetypes extensively in all our projects on UE3, we have/had between 100 to 300 of them in every single project so even a bit of simplifying would pay off rather quickly.
On that note having a details page alone for making these huge set of properties would be much simpler and also easier to manage/create. However people who haven’t used archetypes much before wouldn’t really understand the benefits of such simple system.
That being said though, unfortunately I don’t think Epic would do it anytime soon, maybe even ever. We have to either keep using it as is or add it to the engine ourselves at some point.
