Ever since the series wrapped up in terms of film, I pretty much moved on from the franchise. Never thought about it until one of my friends told me about the author regretting Hermione and Ron as a pairing and I was like:

You're just
now regretting? I understand her reason in having Hermione end up with Ron, she wanted to avoid the cliche of the main male character getting the main female character. She wanted to avoid the inevitable outcome. But as said within this thread, change for the sake of change, is almost never a good thing. Especially if you don't know how to turn it into something decent for the story.
But that was one of the most natural pairing outcomes. The books and even more so, the movies pretty much show that the two have a better pairing than anything involving Ron. Which I find kinda sad for Ron.
