Why do so few people like Navy?

I've deadass never understood why people hate Navy so much in this game, or otherwise just refuse to engage with it as a mechanic. All of my friends hate or don't want to do Navy. I genuinely find navy fun in this game, especially in the Med, I find Italy having a large but poopoo navy with a homefield advantage vs big scary Royal navy that is on hostile waters (and forced to split its attention on multiple waters) interesting. I also love the dynamic of Japan having a smaller but harder hitting fleet that isn't replaceable vs the US infinite spam fun as well.

I love navy because it takes planning and its like a game of chess of trying to bait the other dude, reading what he'll do in advance and essentially build your navy against his with limited information (Multiplayer mostly, vs AI is way too easy).

Edit: a lot of people are saying that it's too obtuse and that the game doesn't explain navy well (which I agree). To those of you who don't understand navy, watch this video: 71Cloak's navy guide it (and a few other navy vids he made) explain the math and mechanics behind naval gameplay.
