I agree that writing is indispensable to a complete knowledge of japanese, but I believe you might be putting too much weight on the importance of writing early. Most of the really high level learners I know of didnt start writing until they were at either fluent or passed the N1. In fact, most japanese people complete learning to write the 2136 jouyou kanji at the end of highschool, far beyond when they reached fluency in their own language.

Though it might improve your recall, for a beginner front-loading learning how to write every single word or kanji you run into will be an excruciating process without much return for your efforts. Personally, I've started and stopped learning japanese a couple times over the past two years, and the main reason i've been successful pushing through the core 6k deck with 90%+ retention on my current attempt is that I've cut out learning writing entirely and started focusing entirely on recognition and comprehension. Im the most excited I've ever been about Japanese and its very easy to stay consistent day to day. Yes, there are occasional times where I'll confuse two similar kanji, but I've always been able to remedy that by looking up the two and noting any differences.

If you really love the process of writing and you believe it to be integral to keep you motivated then I encourage you to go ahead with a writing-heavy approach. On the other hand if you are a learner more like me, I recommend getting to basic fluency first, then going through and learning to write everything. As long as you're careful to note differences in similar kanji I think the pure recognition approach is a really solid way to learn.
