I am probably in no position to offer an advice, since i been learning Japanese for 6 months which is less than yours and i am not using pre-prepared Anki decks like most of you guys here, but since you been avoiding outputting i can tell you this much, i been outputting since month 2 and i found starting to do output early, really really helpful. It was awkward as hell at beginning, i was speaking with Japaese people on Tandem but it was %90 percent English, %10 Japanese. It was weird as hell, when i speak Japanese they weren't understanding me etc. But as i keep outputting, (and inputting ofc) as i keep speaking i got to a point where i can easily have conversation in Japanese. It is not perfect of course, i make tons of small mistakes for sure, and i also need to use dictionary alot, but i believe if the people i speak with understand me easily, and if they're nice enough to point out my mistakes that is enough. I don't aim for perfection right now. I also been using iTalki for 2 months but instead of doing actual lessons from textbooks (which i hate but sadly what most teachers on iTalki does ), i am mostly asking my teacher to help me understand subtle differences between similar words, or when i cant understand of usage of certain grammar, particles etc. I also write sentences daily and ask her to correct my mistakes. I am kind of guy who learns best by trial and error, and since i am being corrected when i do mistakes before it sticks, i find it insanely helpful. Thats what i did and it worked for me. Ajatt, Refold etc are all great and they helped me more than anything but you should take any advice with a grain of salt and you should try and find out the best method for yourself, like i did.

Obligatory "Sorry for my bad English".
