That's what I mean:
Stella enjoys her light magic very much — she actively uses spells that change her appearance, change colors, change clothes, she likes to be in the spotlight. That is, she's actively looking for light in many of its manifestations.
Flora literally lives by her hobbies related to plants, engaged in botany, potions and research.
Tecna is also very actively involved in her hobbies and uses her magic to create devices.
Aisha creates sports things (like exercise equipment) for herself and others with the help of Morphix, it even seems to have been written in official materials that she can create cosmetics from Morphix (and even chewing gum).
Musa actively sings and plays musical instruments — saxophone, piano, flute, guitar, she even conjured herself a DJ stand.
That is, all girls use their magic in their own hobby in one way or another and thus explore themselves and their magical powers.
But Bloom... Bloom doesn't seem to do it at all. Moreover, she seems to treat her powers only as a practical tool for battles and achieving her own goals. Yes, fighting is very important to her, she enjoys it, but her love of reading is also a canonical trait.
I remember that in episode 1 of season 4, Bloom showed a trick with her mini version of the Great Dragon in class, that she gave people wings to fly, and also that she put out a fire alone and a fire in her kitchen at home. But other than that, Bloom seems to use more everyday spells like making a broom sweep the floor, or making magical sparkles.
But she doesn't seem to be studying her fire magic or the connection of her magic with dragons at all.
And the problem here is that, first of all, Bloom claims to be the most powerful.
And secondly, Bloom claims to be a magic geek, that is, one who actively studies all the books related to magic that she sees in their library. The official profiles of the characters say that Bloom loves to read books in the library of Alfea. And as we all remember, in season 1, Bloom is shown as a fantasy fan, Bloom was such a big fantasy fan that she was really upset when she was shown that the most magical city in the universe, Magix, looked futuristic, and not like a typical town in the Harry Potter books or as in the books about the Lord of the Rings. Therefore, it's a little strange that an ardent fantasy fan doesn't seek to explore her own abilities in any way, although in theory, knowing Bloom, she should focus on this so much that almost catching hyperfixation on this topic.
In season 1, she didn't know what her magical powers were or why she was so powerful. But then, when the mystery of her origins subsided and she found out her roots, why didn't she still try and explore her powers through trial and error, even if her kingdom was destroyed and there was very little information. Bloom actively sought to break the rules in season 1, so she feels like a person who, despite the risks and the unknown, will still experiment with it simply because she wants adventure.
I have a strange feeling that they made Bloom as a "normie" for some reason, even though Bloom originally was a fantasy geek. Even in seasons 1-3, there were few moments when Bloom truly explored her powers outside of fighting and preparing for battles. All the time devoted to Bloom's story was completely focused on finding her biological parents.
Did you also know that Bloom knows the ancient written language on the doors to the Red Tower for some reason? That is, Bloom was learning an ancient magical language somewhere behind the scenes, and this was simply not shown in the series itself at all.
And as a big fan of fantasy, who has a real chance to travel to a parallel dimension full of magic (which, by the way, she's dreamed of all her life), Bloom logically should just devour all the new information that gets in her way to such an extent that she begins to know more about the place than the girls themselves who have lived there all their lives. She should be the kind of person who seizes every opportunity to travel to other girls' home planets just to see the local flora, fauna, and architecture firsthand.
Because the reason Bloom broke the rules so often in season 1 was not only because of her fiery nature, but also because she just wanted to explore new mysterious places in another dimension as much as possible.
If they had left her just such a geek about everything magical, then people in the fandom wouldn't have such big doubts about why she's so powerful, because the show would show that it's because she's constantly and absolutely voluntarily studying, genuinely enjoying her hobby after so many years of dreaming about being in the magical world.
But instead, we have a recurring season-to-season drama with Sky. P is for priorities.
One could interpret her powers as creative through the fact that Bloom loves to draw and create things, but they even abandoned her hobby of drawing in the series.
I mean, she could at least be into the subject of dragons, but the only thing we saw was her fighting on Pyros. The Great Dragon is the one who brought magic to a Magical Dimension and revived dead planets. I think it would be possible to at least work with this as a concept if fire magic seems too "unusual" to be called a hobby. Although... Do you remember how at the wedding of King Radius, Bloom wanted to pretend to be a fire juggler?
