I wish earning Star Gems was easier. Items are way too expensive for how little you can get.
But it also kills me how the items are then bound to you on top of it. Getting us the items already out in Japan quicker is absolutely a good thing, even if I wish the Mission Pass and Fresh Finds Shop were better (Fresh Finds Shop doesn't give enough time-- Mission Pass requires a lot of constant play unless you're lucky if what you want is super close or again, more Star Gem usage), there is no good reason for the items to not be tradeable.
As a side note to the Fresh Finds Shop and Bundles: So often I've only wanted one, maybe two, bundle items so them all being paired into that with no way to separate it sucks.
