Hello developer community^^
I am working on the Import_3ds script and a known issue is the keyframer especially the rotation part.
I fixed the script wich is now able to import animation but it seems that the pivot and rotation part is somehow screwed up for original Autodesk exported .3DS files. However, other exported files from sketchup or libs3ds are imported correctly though. Maybe someone has an idea. I guess it has to do with the matrix transformation wich must be world space for those files.

I added the io_scene_3ds script and an original .3DS file from 3DS Studio R3 with an animation, best result was importing with constraint size 1.0 and all options including world space applied. The animation looks funny, but should not be that way in my opinion ;)
