Is the Duty Finder working as it should?

[EmmaTokyo0212]

Not only did I just manage to level my machinist to 60 USING the duty finder I have moved onto to level something else... but wait my duty roulette for leveling DOES NOT and I mean that because I've been trying none stop for a duty for over a day with no success. It's not even managed to put me into an in progress one either, it had been working fine up until saturday helping me finish my second dps and I'm leveling another dps and all of a sudden I got nothing outta it.
Not only has this become slightly annoying it means I'm kinda halted on even enjoying the game at all. Yeah I have beast tribes and yeah we got the new shiny stuff but not being able to do the simplistic thing of duty roulette leveling is just a joke because I actually enjoy it.

This.

Leveling Summoner to 60, pre 3.1? Quick and painless.
Post 3.1, I go to level BLM/ARC and I literally have to drag another 3 folks with me to get the queue to pop.

My patience with this game (and I've given it a lot) is starting to wear thin and I fear this sub cycle may be my last. I'm sure I'm not alone.
