Man I had the opposite happen. Really liked it up until 500ish where it became mass produced hype machine with the same copy paste genre elements and over the top plots that lasted way too long.

Now I'm at the end where they started unloading action and lore because it actually has a planned ending in sight, so I'm happy again.

But for 500 chapters I was very pissed off at the amount of time I wasted reading it. I signed up for fantasy naval action, not a 700 page fake love story with 500 separate characters in Candyland and the plot progression of a boulder rolling uphill.
