I cheated.
When purchasing the new expansion to World of Warcraft "Warlords of Draenor" you also get a one character level 90 boost.
I didn't get that for my main character (priest), I had a sudden urge to keep her "raw" simply to be able to say I levelled her on my own. :-) But my very first character - warrior stuck at level 70, she deserved a boost I figure. :-) I'll have to have a test run now.
THEN go do some work.
