Disclaimer that we have yet to attempt these dungeons, but we will be shortly and fully intend to clear.

Hard 4 man content is appreciated, and this fills that role, no matter how difficult it is. If you quit after only 6 wipes and decide it's too hard for you, then yeah, maybe this wasn't designed with you in mind and you should look for other content to do. Which is fine, by the way, but wanting it to be nerfed just because groups of people can't do it is why some MSQ dungeons went from interesting to mind numbing.

TLDR: Either give it a real attempt at clearing it (IE: Not quitting after wiping only a few times), or accept it's not made for you and move on.
