Well, it didn’t go quite as expected, but yesterday afternoon around 5pm, I finally hit level 70!
I was on my way to turn in a quest (which would have taken me over the edge), but decided I wanted to be fighting when I leveled (it’d make a much better screenshot than me standing at an NPC) Anyway, so I stealthed and was within a second of hitting the elemental when I leveled due to discovering a new area! D’oh! So much for my action shot.
My pockets were overflowing with about 1950 gold, so I immediately dropped 900 of it for my flying mount.
