If combat sounds had been properly implemented and not rushed as they surely feel this could have worked.
It really looks like nobody tested them in game with end gear. (attack speed plays a lot against the repetitiveness and length of the recorded sounds)
Also some skills will 100% play the same exact sounds again and again every. single. time.
Also as previously mentioned the sounds equalization is really bad. Some are way louder than others and overall louder than the kr version. We hear them way too much in comparison to the other combat sounds such as hitting, metal sounds etc. They stand out too much.
If you don't want to give a toggle for whatever reason, at least work on implementing the combat sounds properly.
