Which kind of problems do you get, because my team and I are exporting skeletal meshes since february without having any problems? 
We use a very simple workflow:
- Creating the rigg (just a ordinary one which is shown in every rigging tutorial)
- creating animations (we also create them like in the youtube tutorials)
- scale everything up or down -> Object - Apply - Scale/Rotation/…
- export it -> Mesh + Armature
- Import it with the base settings (enable import animation)
