Increase your General knowledge.
The skilled players at WoW - TenTonHammer wrote a guide for the beautifully scripted second boss encounter in the Ruins of Ahn'Qiraj (a World of Warcraft level 60 instance), the battle with General Rajaxx. The guide explains all the steps to defeating the General and his guards to progress to the inner areas of the ruins.
Being 8 big pulls means that this fight takes a while to complete. The first thing to know or plan for in this fight is to keep Lieutenant General Andorov and his guard alive. This is for two reasons:
1. They do a large amount of damage and help this fight progress at a faster speed
2. Andorov can sell some nice gear to you at the end of the fight.
3. Most important of all, as long as you have a reputation of friendly or higher with Cenarion Hold he will place an amazing buff on you. The buff heals you for 200 health every 3 seconds, increases your attack power by 10%, and lowers your casting time by 10%.
