Sure. I'm just trying to address one of the weaknesses in the story. No matter what I write it won't matter if it's known that of course everything will work out fine... A little uncertainty is a good thing in that. To take the char I've invested in, would she really be able to cope back in her old body after being an animal girl for months? Of course she would desire it but I really doubt it is good for her, unless magic also gave her back everything, effectively killing the person she was before. One could argue this 'other' was just the result of magIc and not real... But it would be just as much a death, and more so then her original wish.
Jon is not a god able to undo everything. Indeed if this were very realistic he probably should just make it an interesting dream no matter how things are. But this is a story.
Trying to fix things 'could' make it worse unless the wish was kept simple enough. doing nothing is not the worst possible thing that can happen. Generations later people could be fine with it and not know any different. Disabilities are only apparent as its still a human world. I've tried to show that tfed bodies are always healthy and generally less Ill. Disadvantages always balance with a major advantage.
Lately... It's just a story. Please don't use such harsh language when it's already a very complicated plot. The tfs give Experience in states other then human and we just watch it through them.
