I just wish they would generally rework how expert functions, cause the "same dungeon for months to an end" is incredibly stale.

just use whatever algorithm is used for Unreal on every dungeon in the game, give us a pool of one dungeon per expansion, have them rotate weekly. Or something like that.
Or, to make it easier, just have every max level dungeon of the current expansion in the rotation for DR Expert.
But that would mean deviating from the plan that was created in ARR, even though parameters have changed.
