Thanks for the responses folks. I'm queuing as a DPS and I'm mainly queuing for story content fights like Leviathan and Ramuh Trials as well as turns 2-4 of Coil of Bahamut. I queued with an old healer friend of mine after this thread was made and got more or less instant queues. So I'm guessing that this server just has an extraordinarily imbalanced healer/tank class to damage class preference.
