The healer queue has gone up since the patch hit. I believe they did adjust how Duty Finders search and match players together and that would be another factor to some of the delays healers are experiencing on top of what's been listed here. The only real time I get instant queue's on healer is when I'm going for Trial DR and I feel queuing for DPS (especially for Midas normal) to be faster.

...now if I only I can drum up the courage to trust a random DF Healer and queue on something other than healer. lol
