any plans to fix DF wait times?

Unfortunately for you, the timing is bad, with the Gold Saucer dropping yesterday, a significant portion of the player base is doing that instead of queue for daily roulette.

The only fix, is has been to encourage more players to queue for these as tank/healer, SE has increased some rewards for playing as those classes but definitely not enough to spur true migration.
One daily low level roulette as an "In need" class (Tank 85% or Healer 14.9% or DPS 0.1%) only provides additional 7500 Gil and 219 GCs to that player. Since Gil and GCs are so easy to come by, this is not enough incentive for people bother. The roulette, pays SOL, Poetics and GCs bonus regardless of class.
Roulette In Need Bonus

A true incentive change for the In Need bonus would be adding more SOL, Poetics, Allied Seals or MGP. A better incentive would be to allow the bonus more than once per day.
This is not done because SE does not want end game characters just farming the Low level roulette for these currencies, which currently must be achieved via other higher game content.
The In Need bonus does provide extra Gil multiple times but as I have already stated, this is a very poor incentive to an end game content player.

My best advise is to find a Free Company that will help you out with those choke points in the story.
FYI, in the older days before the roulette and bonus, queue times were 2-4 hours for what you got in 45 minutes. As you can see from this, the existing roulette bonus did improve the queue times. They just are not good enough yet for everyone to be happy.
