Nope, the random dungeon finder got borked from the content patch and every week they been trying to fix it to no avail. Even if you're a tank, you can expect to wait 30 minutes or more before it finds you a group. It has gotten slightly better with each new update, but you'll won't see pre-DB timers for tanks and heals where things would pop within the first 10 minutes. They supposedly fixed the big group issue if you ever ran into that, but the problem I hear is that if you have a group of 4 and someone drops out, the game refuses to look for another thinking your group is full so you have to go as 3 or leave and take the 15 min penalty.
