Toilet drain pipe issue

So I had just bought a house and passed inspection with no problem. A month goes by and my bathroom tiles start warping, So I pull up on the tiles and find that the subfloor is completely rotten and very wet. I replace the subfloor but find that there is about an inch of give on the toilet flange to where I can pull up and go to the crawl space to check out the pipe and find that the drain pipe is resting on an old cast iron pipe with plastic wrapped around to "cushion" it. Do I need to replace it or do something to it? Also, I believe the original leave was simply because the old wax ring hadn't been changed in atleast 10 years? But I'm not sure. Also, I have pictures but can't figure out how to upload. I can message them, I think. Thank you!

The toilet flange should be secured to the subfloor and should not be able to move at all. Once we can see the pictures we can better offer advice.

As you can tell, the pipe is unsecured and the drain is simply resting on it, as it travels out.

Well, you can fix the support problem with either plumbers tape (metal strapping with holes every inch) or J-hooks

But the pipe should probably be done correctly as long as you're working down there. I really don't like the PVC to ABS to PVC to rubber coupling. I would cut back the PVC and replace with a correct PVC elbow, a length of PVC pipe up to a new flange screwed to the floor. All done with purple primer and PVC cement.

As long as you're going through the hassle of replacing the subfloor, I'd spend the extra time to fix the plumbing too.
