It’s been a while since I looked into installing/reinstalling HA but AFAIK using anything else than a Raspberry Pi seems discouraged, which is… discouraging.
I don't think that's the case, the docker containers are still going to be officially supported, and you can run those on any hardware.
6 months is not "absurdly" short considering it won't suddenly stop working. It's an open source project, 6 months is fairly reasonable for such circumstances.
The difference is doing it for yourself vs. doing it for the entertainment of others. Everyone is free to take performance enhancing drugs for themselves, they shouldn't be free to take them for a literal festival.
It's difficult, but good. I'd advise trying to play with the default settings for a bit - you need to engage with the parry mechanic to have a chance, but if you don't, you lose out on lots of fun. But if you can't make it work, lowering the difficulty is definitely a good option!
That's why you gotta get one of those side sleeper pillows (I've got one without a waifu, but to each their own). That shit is straight up magic.
