Have you ever considered that people might like a challenge just for the challenge itself?
That you dont do this content "just for the storyline" - and that not everyone wants to clear it for prestige and people being like "Oh, wow, so impressive that they managed to beat that!"

This content doesnt need adjustment, it doesnt need nerfs - what it needs is the people who do it be willing to face a challenge once in a while, to learn mechanics, work as a team and beat the content. It was never intended to be really queue in with randoms and be a faceroll-one-shot-clear, just as much as the current Savage raid or EX-primals arent expected to be that.

Please, just leave this content untouched so that anyone who wants to have a challenge in the game, has one.
Stop crying because some content in the game actually requires you to pay attention for a change.
