Either Go back to 2 dungeons per patch (1 hardmode 1 normal dungeon), OR they need to change expert roulette so it's not just 2 dungeons.

I would only be fine with 1 dungeon per patch if they made expert roulette not locked to 2 dungeons. Perhaps change it so that it's minimum iLVL runs and chooses from all the level-cap content of the expac. And then make the level 90 roulette have all the level cap dungeons but without enabling minimum iLVL.
