Sure, It’s a personal problem but who created this massive issue, Reward Devs.
Chimes acknowledge this issue back in 2022 when they started to change it, because it was even worse that now, however; I think that this kind of threads are needed, so maybe Reward Devs finally decide to address holidays with good rewards that are behind a challenge, a questline…etc and it’s a celebration of the event instead of 15 days of attempts if you only do the 1 attempt that you don’t know the drop % or the increase %.
Also, Devs could just remove the option to drop in alts but they didn’t proceed with that 
In my opinion, Devs should provided a good experience, it’s a game, I’m glad difficulty increase but this should bring some kind of BLP.
A lot of players are frustated because even if the drop % is 99%, you could hit that 1% of bad luck for years, we don’t know anything, like if the increase per day resets every year 
it’s in your best interest to repeat this event every day on as many characters as possible. That’s… mathematically correct, but not a great experience.
