I also played Elden Ring recently. I wish I could share your dopamine rush because I never had one during the playthrough. Certain bosses caused so much frustration that the net sense of achievement for the game was negative for a decent margin. I've also played Dark Souls and Sekiro and I found them better on this aspect. After beating them after an extended period of struggling, my thought was not "I finally got it" but rather "I hope there aren't more bs like this".

Shameless plug and possibly spoilers: I wrote about this in my blog https://asukawang.com/blog/bitter-masterpiece.
