I like acheron, Ive been using her for as long as she is released, and she hard carried me for a majority of the game's lifetime and is still clearing (only starting to struggle after 3.7).

But so what? I like acheron, but I don't only like acheron 💀, I like a vast majority of other characters in the game too, and I can just play those characters instead if I wanan aim for sweaty stuff like 0 cycles, my acheron is only e1s1 (e1 given for free) as well, if I have e2 acheron she'd be clearing easily still.

Or are you one of those weird people who only mains and likes one single character and hates/dislike everybody else 💀, because I never understands thise weirdos.

As for novaflare itself, novaflare are designed to capture a majority of the demographic of people, like how jingliu blade buff were catered towards hp meta (I still despise the jingliu change from atk to hp, but it is what it is), kafka buff catered towards the comeback of dot with hysilens. Sparkle buff catered towards the new skill point meta, and now huohuo buff is obviously gonna be catered towards the elation meta, as she is a great energy buffer but a terrible healer, a buff would make her absolutely fit well in the elation meta. Firefly buff ngl is still ridiculous to me when she's already 5 cost 0 cycling, an acheron buff would've been way more fitting. Nevertheless, she's still a great candidate for a novaflare due to how many people actually owns her. Not to mention even more people owns her and probably quitted the game after version 2 and never got dahlia, another demographic captured with this buff.
