we need content with difficulties between dungeon and ex/savage

[Theodric]

It’s the lack of any difficult 4 man content that’s the issue. There is absolutely none of that in the game.

This could really be a place where I think everyone sees a hole in the content and could also maybe satisfy the OP as well as a large % of the playerbase instead of just more ultimate stuff which only .5% of the playerbase will ever even see.

I'd argue that POTD and HOH are reasonably difficult, at least when it comes to the higher floors. Though admittedly a lot of that difficulty resides in RNG. I often wonder how much more successful it would be if it wasn't such a pain to find a group.
