Sorry, I should have been more clear.

I keep running into the problem of "this group would be fun" and I don't have the group. For example, I'm currently leveling warlocks. In a few months maybe it will be hunters, or mages, etc. If I knew locks were going to be the last group then I'd be ok stopping, but I'm worried about the constant adding on of new toons.

There have been some valid points made. The leveling time from 1-60 is small compared to 60-80 so if I really want to do this then maybe I should save the money and keep the current accounts.
