For your question about what people wish was different about Japanese learning materials, something that I've always disliked about most resources is how they teach 'conjugation' because it's unnecessarily complicated. It doesn't help that Japanese 'conjugation' doesn't resemble at all what you do in English, Spanish, French, German, etc. because it's not really conjugation like that. It doesn't indicate number, person, mood, or tense beyond the simple past and non-past. This video is honestly the best resource I've found for this: https://www.youtube.com/watch?v=FhyrskGBKHE&list=PLg9uYxuZf8x_A-vcqqyOFZu06WlhnypWj&index=8 , and I wish verbs were taught like this in other places too.
For me, learning verbs in the ない form first really helped, but I know that other people find different ways easier. I have an explanation why I do this on my blog.
Conjugation seems to always be one of those topics where no one is satisfied and everyone wants a better way. :( Waiting for the Matrix downloading right to the brain on this one!
Thank you for the video, I actually haven't watched any of Cure Dolly's stuff, but I've heard that her videos are pretty alright, if a bit dated on a literal technical level, not subject level. I'll have to poke through some of them and see if any of the information sticks.
Again, thank you very much for answering my question!
