Leveling Dungeons

So I have a number of 80s now and I have been finding that when going into leveling roulette that even with a party of 70+ I am not seeing any dungeon past stone vigil. My first 80 (DRK) I got 71 and higher when unlocked but since then I havent seen anything past stone vigil. Am I the only one experiencing this?

I know I can use trust dungeon to use my new abilities as I get them or just que for the level dungeon I want. I really just want to know if I have really bad luck.

I'd love to see part of the algorithm change so that you get within 5 levels of the lowest in the party but i am not a programmer so i am not sure if that would even be possible.

Well since apparently they added min ilevel requirements for leveling dungeons, I assume people are doing the same crap they do with alliance raid roulette in order to get lower dungeons, because it's 'easier' and 'faster'.

However, today I got Doma Castle for my roulette.
