I think the event furniture like the Mushroom and Tree's Bounty sets being locked behind balloon drops is my biggest problem with New Horizons, even more than the clam/bait crafting issues. There are currently *3* separate event sets locked behind balloons that most players will likely barely see any of, with *30* diy recipes in all. I grinded to get all of the Cherry Blossom recipes and it took about way too long, but this is just a different level from even that.
Even if you're grinding out balloons on the beach using the "wait for the 0s and 5s" method, it'll still take REAL LIFE DAYS to get all the recipes. I think I have like 7 out of 30 right now, and that's with playing quite a bit over the fall without grinding balloons.
I think this might be where I'm just done - I need to let go of my OCD and just forget about getting all of the furniture, because it's not worth it. I love this series, but I wish it didn't have such a weird fetish for luck-based grinding (I will say this isn't quite as bad as waiting to get the Public Works Project suggestions from villagers in New Leaf, which took me well over a year)
I wish they'd just let you buy the set or recipes with Nook Miles or come up with some more fun/interesting way of getting recipes than "hope that maybe they fall from a balloon" - the least they could do is bump up the chance that a villager crafting or a beach bottle gives you a seasonal recipe during the period they're available, since it's just really deflating to get repeat normal recipes over and over when I'm trying to collect the seasonal ones, or even the handful of normal ones I still need like a few pieces of the Ironwood set, after like 9 months of regular play.
