This is more trash that requires you to move quickly and carefully. You're forced to move quickly because there's certain (very weak and very low in hitpoint) npcs called Amani Scouts that your raid leaders will mark for you. You'll be commanded to kill them (And they always take priority no matter what you're fighting. You have to be ready for a scout constantly). If you fail to kill a scout before it reaches a gong, it will spawn two adds. This is tedious, and must not be allowed to happen. 

In this trash area you deal with a type of troll called a Flamecaster. These are a very deady type of troll and must always be CC'd. Another thing about them, however, is that they're very, very MC'able. Shadow priests usually will control these. They can be used for dps, or you can have it tank the group it belongs to until it dies. Either way, you don't want to fight these in a group if you can help it.
