I'd totally recomend it.
I find reasonable that people didn't like Ashes of Ariandel, I like it just a little but if you finished the main game and want some extra items and boss fights you could get it.
About The Ringed City: This one is cool, it has 3 different areas and lasts more than AoA. The areas mainly focus on being the expected end of the world that they talked you about during the lore, where the lands converge and time is an absolute ♥♥♥♥♥♥♥♥♥♥♥. The boss fights are nice and hard as your ♥♥♥♥ after hearing the Firekeeper say to touch the darkness within her and the music is masterful, but it could feel more like an ending to Dark Souls on the surface.
You can get a not so good and an awesome DLC at a dollar more costy price than the Awesome DLC so get this and have both instead!
