It may not sound correct, but I did do this when I used to play
WoW intensively. Well, this is durotar soo go Troll/Orc. Do all those quests from Valley of Trials ~ Razor Hill. You should be a decent level. 10-12? Well, now it's time to grind. Grind off of durotar razormanes until you get 12. Once hitting 12, go to the NORTHERN Barrens. Just grind on lvl12-15's. This may be a challenge, but if you're a healer, it works great. I do suggest looking at other guides also because I played
WoW like the first Week it came out until about Mid-2006 soo I haven't played for a while. I do consider starting up again.
