[USER=“3140864”]MostHost LA[/USER] Who needs Rigify though haha. It’s great to learn the basics with i guess, but for serious animation you can’t do anything advanced without re-rigging the whole thing.
We can’t really expect the ‘Epic’ people working on this to cover real Blender side rigging and animation, they will just stick the mannequin on Rigify and be done with it.
Just as long as they expose those FBX export settings and don’t force any unit scaling everyones already existing add-ons should be compatible one way or another 
Edit: I also want to back you up on the whole collection thing, it seems like one of those good ideas that’s just going to go terribly wrong.
