Okay so In Redridge Mountain there is a quest (Quest:Breaking Out is Hard to Do - WoWWiki - Your guide to the World of Warcraft)
Pretty much once u do about 4 quests in this chain you have 4 npc's following you around buffing you hitting 50's on mobs and de-buffing them.
Using boa's and being a mage I pretty much 2 shotted everything in redridge anyway but these are extremely helpful and they follow you around untill you logout/hand in quest/leave zone. So you can use them to 1 shot mobs easily for very quick levelinghope this helped.
