Honest question: is WaniKani a waste of time?
I'm a Japanese beginner (N4) and I've been using WaniKani for the past 2 years or so (I'm currently level 30 at it), and every time I use it I feel like it's a waste of time because I can't really see my Japanese improving in almost any aspect. To be fair, I feel like my reading comprehension is improving little by little, but that's about it.
I decided to post this after learning this word: 衆議院 (house of representatives). I don't remember ever saying such thing in English ever in my life, so I'm not sure how useful it is to know this term in Japanese as a beginner. Some of the other words I've learned recently are 逆説 (paradox), 新婚旅行 (honeymoon) and 電気柵 (electric fence).
Am I wasting my time? To me it's not as simple as "just stop using it then" though. As I said earlier, I can see my reading getting better (extremely slowly, but still). And I don't know anything better than WaniKani. Duolingo is far more useless for Japanese.
So, is WaniKani bad or is it just skill issue on my end?
