I've been playing TotK. (Working on 100%'ing it. I've got 52 Korok seeds left to get, and no guides. Probably still have some sidequests to do.)
I miss windbombs so much. The Tulin gust thing is great and all, but it's really aenemic compared to a good windbomb.
I never got any good at BTBs. Probably why I never tried to speedrun plain old Any%. (I stuck to a couple of individual levels when I was speedrunning. I'm this guy if you're curious.)
Also, this might be a hot take, but I believe with all my heart that BotW is a "better game" than TotK, but not on purpose. BotW feels kindof unfinished, but I still don't like TotK anywhere near as much as I like BotW.
I don't really see myself replaying TotK much. I've played BotW like 4 times now (not including speedruns.) And 100%'d it once.
Edit: Oh! Whistle sprinting too! That was the first thing I tried as soon as I started TotK.
