I really appreciate the work the writers put in, and I don't want to request any specific content because obviously that needs to be either tailor made or commissioned. But in a very general sense, I would love to see some more titillating and involved transformations like The Treatment. As it stands, all the transformatives I've encountered are very simple "you are now 'insert parser here' congratulations!" Which is obviously understandable since it's hard to make species transformatives sexy, or involved writing for vague physical characteristics.
I tend to be very conservative/humanistic regarding transformations, mainly just acquiring ones that provide sexual boons or accessorize like makeup, tattoos and jewelry; but I am a fan of the ones from Trials that have narrative and erotica directly involved. At the moment I am basically a cow girl/wyld elf hybrid (for Hashat's content), since I don't personally care for anthropomorphism. Now that I think about it, the ability to become an actual elven hybrid would be nice for mixed content.
Mostly this spurs from being a bit let down by the "Bimbo Brew" in comparison to some of the exciting transformatives you can encounter in Trials, like at Poe's Lab and the "sexy drugs" like Gush. I saw someone mention there being a treatment style transformative planned for Khor'minos, which might just be hearsay, and I also saw Savin mention a non corrupting bimbo transformation being planned, both of which, if accurate, are right up my alley.
Selfishly I would adore seeing more bimbo sex scenes, as that is some of my favourite content in Trials (in comparison to Bimbo dialogue, which can be inconsistent). I like all the variations for bimbo dialogue I've seen in Champions so fair, because it emphasizes empathy, joy and femininity without being condescending or mocking like some dialogue in Trials can be, but simultaneously I haven't encountered any erotic content tailored for it, and it is sometimes impossible to tell what causes dialogue to trigger because of the lack of a public github, such as if cunning is actually working.
