Frostmourne New Season - Time /played to 80

[whatever23]

As per title, whats the average /played to 80 and whats the realm first /played to 80 usually in new seasons?
I have read in several spots that questing > dungeons, is this also true for a tank / healer with instant queues?

took me 18 hours on my pala to get to 80, leveled as ret and queued dungeons from 20-58, I don't recommend doing dungeons for leveling in outland or northrend. Outland especially is hard and takes alot of time while it just goes so fast when you're questing with flying mount. Tanks and healers don't always have instant queues but they are usually within 5< min.
