> stuff they randomly throw at you without any explanation
That's kind of their approach. I agree that in case of Japanese they could do better. E.g. if they explained what is explained here: https://8020japanese.com/japanese-sentence-structure/ - and they have space for such texts, but they are not using it for Japanese - it would save me some frustration and trying to figure out what these weird things are doing inside the phrases. Once you get the principle, it kinda clicks in place. So with the help of some other sources, so far it's not too bad for me with Duo and Japanese I feel. Though of course I don't think it's possible to use it alone without some auxiliary materials.
