i got to 70 on my shamans in record time. I have started mages warlocks and now hunters, id have to say that 1-20 nis the WORST levels, id almist rather do 50-70 again than 1-20 lol, they are SLOW, u get no cool abilities, and they are BOOOORING. i FLEW through lvl 40-70 on my shamans, and i had a blast doing it. getting to lvl 20 again was horrible :P try and get to 40 or 50 and see how u like the change of pace =)
