Hi there,
You have problems generating threat? You need some more initial aggro? Are those damage horny DPS'ers constantly overnuking at the start of a battle? Or are you looking to find a way to increase your DPS? Fear no more!
You can start off a boss fight having 80 rage, without even having to fight or take a huge hit for it! All you have to do is get the following 2 items;
chestpiece from a level 20 warrior quest called;
[Alliance] Furen's Armor (http://www.wowhead.com/?quest=1782)
[Horde] Brutal Hauberk(http://www.wowhead.com/?quest=1848)
-[Horde] Brutal Hauberk (Brutal Hauberk - Item - World of Warcraft)
-[Alliance] Fire Hardened Hauberk (Fire Hardened Hauberk - Item - World of Warcraft)
belt made by leatherworkers-
Barbaric Belt (Barbaric Belt - Item - World of Warcraft)
What you do is, before a battle, you equip these two items, use them, and gain 60 rage (30 rage being a druid, seeing as druids cannot obtain the chestpiece).
Pair it up with a warrior's bloodrage, and voilá, you have 80 rage to start a (boss) fight with!
Don't forget to re-equip your normal items, ofcourse hehe, I speak of experience
Enjoy
