This is without the 5% XP ring from fishing, but otherwise full Heirlooms.
My leveling times are listed below:
1-70 - 39 hours (played)
70-85 - 26 hours (played)
85 to 90 is a long process, about 30 hours played. Perhaps more.
Up until 80 I played every DG once to get the quests and hand them in.
It's about 100 hours /played to get from 1-90 with almost full heirlooms. (without RAF)
From 80-85 you will earn 1700g from quest rewards and, if you vendor the items it will give about double that.
