It feels that a lot of hardcore focus tends to be specifically directed towards the 8 man raid of whatever patch is out. In the future it would be nice to see a hardcore focus in a 4 man setting.

Has there been any thought to adding an interim 4 man dungeon that has the same difficulty and takes the same kind of coordination as an 8 man raid?
It would be nice to see something that could be used as a way to get interim loot for raids after the weekly lockout for the endgame raid is finished. It would also give a repeatable challenge for those interested in a harder dungeons without the need for finding a static.
