It's not worthless at all, and you cover a ton of ground with it.

One of the most difficult things for a learner of kanji that's not Chinese (or to a lesser degree Korean) is that when you are learning a character, you are typically learning
1. its meaning
2. one reading
3. another reading (plus more if it has situational uses)
4. this glyph that you don't really understand how to parse

Heisig targets the hardest part of this, the glyph, and gives you a comprehensive system for working through them that builds into a fast, efficient system for you to incorporate more characters as you work through it. By the end, you can easily parse, categorize, and mostly even understand their meaning (with some notable exceptions).

Once that, literally the hardest part of reading a kanji is in the bag, the rest comes easy. It's amazing how quickly you burn through vocabulary, and it's worth every minute invested if you're actually serious about engaging with written Japanese beyond children's comics and VNs.

Sorry it didn't work for you.
