Well, I wanted to address the question you posed.

The whole "Bloom Arc", explaining her past, the Dragon Flame, and her connection to enemies stopped with the Secret of the Lost Kingdom, and was reintroduced for a bit in S6. Domino is restored, and it'd be impossible to expand upon everything without the seasons getting repetitive.

Seasons 4-7 are themed, and that's the direction the series seems to be taking, because Bloom's story has mostly been told. They're trying to expand upon other parts of the Magic Universe now, even though it may not seem like it. They covered the history of Earth Fairies, ocean gates and their lore, legends, and how animals play into the series in a few years. I may not have noticed it before, but they're actually expanding upon concepts quite a bit, and I have OP to thank for helping me realize that.

As for Season 7, I don't know why they chose animals...seems like a better theme for Season 5.
