When you write out a Kanji stroke by stroke, you only build the skill of learning that one Kanji's stroke order, not its practical use or sound. You also must continue writing that Kanji out in order to retain that skill, which becomes a significant time investment for complicated Kanji. Like any skill, it only sticks with you if you use it. Ask yourself: are you ever going to be in a situation where you need to write Kanji? Most people these days, even in Japanese, type rather than write. The Kanji ๆ for example is very complicated to write, but it is only two key presses, ใ and ใ. I learned this one through reading, and I have a good feel for its meaning. I wouldn't be able to write it out, but I doubt I will ever need to. It is simply more efficient to learn by reading, listening, or watching, unless you need to learn how to write by hand.
Also if you are not encountering that Kanji anywhere except Anki, then you need to ask if it is even worth learning.
