Well done. Impressive feat - something I certainly couldn't do - I get bored too quickly. I had many alts (14 or so) in WotLK, but couldn't get more than 1 to 85 in Cata, then stopped - I did have 5 accounts, then consolidated all the toons to 2 accounts, however.
It amuses me when people scream "no life" - it just takes focus.
heck, can't tell you how many mmo's I play and "could" level faster, but I get distracted too easily. I'm over 24 hours in on ESO for example and only level 12.
