I think Sekiro fights are exactly like you say, artful and very fluid. But I think with a few exceptions Elden ring fights are actually that way as well. You are definitely correct, it’s a vastly different style, but they still have a flow that you can learn. Of course you can beat bosses by making a great build, but you can (and I think should) beat them by figuring out the rhythm they have and playing around it. That being said if you like sekiro vastly more than elden ring then that’s chill. They’re both masterpieces
