If you play ... lets say 6hrs per day constant ~ you easily get up to lvl36 in half a year cause of double XP now.
I managed to retire on the 1.1.13 - got up to lvl35 in june [without double xp] thats half a year.
Huh, I played a lot and it took me more than 2 years (2 and a half?) to reach lvl 35,7. And around 80%, if not more, of my xp I got on rageball, where I was sharing banner firstly with Makelele and later with Barabe guys (which means I had almost constant multi), and in Strat 4. lvl 35 in half a year? You had to play plenty of strat battles
