I'm not totally sure if things being Fate locked or seasonal is more annoying (having to spend real money I can hardly afford vs having to wait for a narrow window of an entire year), but there's a clear most annoying category: Fate locked and seasonal items.
Really sucks because it feels like there's a lot more of them coming up with the new stats, and ofc maxing them is generally useful in one way or another
That or they're from the ambition endings, and don't even get me started (gigantic echo/action dumps, unbalanced feeling items from the different ambitions, etc).
