In Blackhoof Village, Dustwallow Marsh, there are Tauren. The Grimtotem Spirit-Shifters are lvl36-ish and summon 2 wolves from time to time. On my 37 rogue, these wolves still give me 96 experience per kill, and I think they only have 1 life (I 1hit em). So for any healing/high armor class/pwners just keep the spirit-shifters alive and keep killing their doggies. You can just let a lvl70 stand in front of 10 of those spirit shifters (not doing any damage) and then you just kill all the wolves they spawn Easy and fast experience.
