I definitely didn't watch an excessive amount of Sailor Moon in my childhood! No magical girls here... and Gina can't even use magic properly, only summon spirits... sooo...
A Magical Girl anime, but them transforming also means getting big muscles, now that is something I would watch. 😋
Also, while Stella can deal excessive amounts of damage once her flank is cleared, using her skills defensively was always meant to be a viable approach too. So I think you didn't do anything wrong there 😉
