Comments were more of a bonus that I enjoyed looking at after I watched an episode. You could sometimes find some very interesting comments.
However, what they also removed is reviews. And I used that to choose what animes I was going to add to my watchlist. Without that, the website is pretty much useless, I rather watch them elsewhere if I have to use another website anyway to get the reviews.
Yeah. I use KeepassXC on my computers and KeepassDX on my phone. All synced with syncthing and it works great.
