>>114895837Lavabending was actually shown in ATLA, just performed by an avatar, so everyone logically assumed it needed fire and earth bending, but it was already there, it just never happened apart from that moment
And in the case of bloodbending, I was just performing a thought experiment, but I agree, it's annoying close together to metalbending
Wait, no, as Hama discovered it around 30-50 years before the Gaang shows up, so there is still quite a bit of room
which is quite little still on a scale of 10000 years
