The lesson Blizzard is teaching the majority of the playerbase is, if you can queue for it, it will be easy and quick and relatively efficient. You are not expected to be skilled. You should not expect to wipe much. To go back on this would incur such wrath and backlash as has not been seen in some time.
Just look at pre-nerf Garalon, as has been said many times already. When I downed it, I felt a small bit of accomplishment, as with downing a Normal or Heroic mode boss. It had required teamwork and relatively good performance from the group. Most everyone else seems to have thought it was completely unacceptable to have wiped more than 3 times on a boss, especially if they did not receive an epic for their time.
If you can queue for it, it can't be challenging. The purpose of random group content is to clear it, not to work through it like progression. The "just don't queue for it" argument won't work, simply because it doesn't. Players will queue for it and expect to be able to do it.
