I'll see how much/less it can do than than a regular backing plate on a rotary after I get mine and run some more testing.
I don't have all those other issues you mentioned when using my rotary in it's normal fashion, once I learned how to use it and to watch what I was doing

. But for me it's all I've ever known for cutting and polishing and could never get the hang of a PC.
I hope more people get one and we can really compare notes.
