Is the wait time shorter in the duty finder for tanks or healers?

Guys, Duty finder is cross-server. It doesn't matter which server you're from!

Also, it's just common sense that Tank and Healer takes less time to queue up. There's a little over 2 times more DPS jobs than Tank or Healer jobs. Do the math.

DPS: MNK, DRG, BLM, SMN, BRD
TANK: PLD, WAR
HEALER: SCH, WHM

On top of that, I'm sure if we'd do a survey, people would prefer stab stuff in the face rather than working on gathering them up or healing people.

The data centers were shuffled around in 2.1, that list is no 100% accurate anymore.

In my experience on Aether, it's almost even at level 50, leaning a bit towards tanks. As a healer I'm getting instant queues for roulettes surprisingly often, and any time I don't get an instant queue it's never more than a minute or two. I've also run into situations where queueing as a tank isn't quite instant, and also has a minute or two wait. So it seems safe to say that both tanks and healers will have very short queues for most level 50 content (below level 50, healer queues are much longer for some reason).
