Being one of those who complained about this before, I can feel you somewhat, though I think it’s not as dramatic anymore. Some of the first World events were definitely over too fast, but well, they were trying out something new.
I think that’s an exaggeration. Most of the world quality events are repeatable, meaning they’ll happen again. The one exception is the Summer event, and I thought this year’s went a lot better than last year’s:
I thought they addressed this quite well in this year’s summer event (Museum) compared to last year’s (Grand Clearing-Out). The pacing was a lot better, and you weren’t really punished for missing out on one of the stages. Yes, if you missed the whole event, you probably haven’t gotten any of the special rewards. But I feel like I could live with that if it had happened to me. And maybe it’ll return at some point in the Waswood Calendar!
Yes, you will sometimes miss out on stuff. I have (the Crocodile Hunt during the recent Museum event was the first time I’ve been able to participate in a Zee-Creature hunt. I missed all of the Lifeberg and Crab events).
But I don’t think you ever miss out on really important things. Earlier this year there was something about an Urchin war that I think everyone felt was completely underwhelming. I don’t remember the specifics, but I kinda took a look at it and decided “not worth it” and returned to what I was doing at the time.
I have felt like that a few times, but in general I think it’s manageable. If you’re a completionist you’ll probably feel harder about this, but I really don’t think you miss meaningful things (the exception was last year’s Clearing-Out, but that was the first World event they did. This year’s was far better paced).
The bigger problem for me is constantly having to look out for information about what is happening. Like, I cannot imagine playing this game without constantly referring to the wiki, or taking a look at these forums (or Discord) several times a day. And even then you miss things because sometimes FB are just a tad lacklustre with announcements (they always have been though). But I don’t think that’s something that’s going to change.
TL;DR: I don’t think you need to feel stressed by the game. That’s not worth it. If you feel like that, maybe just take a break. Everything will still be there when you return.
