Healer queues taking longer than usual?

Tanks get nerfed in 3.2 > People stop playing tank > Queues get longer.

That would be true assuming an equal distribution of tanks moving to queue as healers AND DPS. The current queue situation has <30 second waits for DPS and upwards of 15 minute waits for healers. I've been testing this off and on since 3.2 since I noticed the stark change

Assuming a tank exodus, this would only happen if every single tank is queuing as a healer instead, which is highly unlikely. A more reasonable explanation is a change in the sorting algorithm; one that bumped healers down the list to have the lowest priority when being matched. It's a good time to play a DPS.
