The quests are the same from 60-80 but there are new ones from 1-60 and 80-85.
It was never really the same quests over and over again though, there are thousands of them, they can't all be hugely different.
My mistake,i didn't put it right.I meant that you always needed to go to the same regions,after your startersarea.And to be honest,i restarted Wow 3 times in the meantime,and i still remembered most of the quests...
