On my main (60 Priest Zenzaya: Horde: Staghelm) I have totalled 41 days and 10 hours of gameplay in a year and a half. That is the total after I had to take off when I was sick (about two months) and then when I had to finish school (about a month). Also there was the month I didn't have internet and about a month when the new patch came out.
I have two mages on two different servers that are about level 50. Then there are tons of characters that are around level 30 and countless toons that never got to level 20.
Good god, I have no life.
