We just had a thread about this. The Ju-52 is about as far down the list of priorities as you can get. Even the B-29 would fill more of a role than the Ju-52.
In the Mains it would see only limited use. It has light defensive armament, but not that much better than a TBM. And in a MUCH slower aircraft. In fact, it's slower than even the C-47.
In scenario use the Ju-52 likewise has limited usefulness, as even C-47s rarely--if ever--see use. Certainly FSO hasn't used C-47s since my squadron has been flying them. Furthermore, I've RARELY seen base capture turned on in AvA when I've popped in, so once again there's not much for it to do there.
Would it be nice eventually for nostalgia? Sure. But there's other aircraft that are FAR more important and useful missing (if you want a German plane, try the He-111).
