The Vault of Archavon is a raid dungeon found in Wintergrasp Keep in the World of Warcraft.  VOA, as it is commonly referred to, is a relatively simple raid and one that many players get to experience since it is very simple to group for and complete.  As of today's patch it now contains four bosses with the addition of Toravon the Ice Watcher. It contains very few trash creatures that need to be dealt with and all four bosses can be completed quickly.  If you haven’t beat the raid yet, maybe it’s time for you to learn all the strategies and defeat it before the next expansion comes out!

The other thing that makes VOA different from other raids is the loot that is available there.  Each boss can drop PvP or PvE gear of varying quality, for any class or spec in the game.  This makes loot quite random, as a piece of gear may drop for a spec or class that is not present, or all PVP gear could drop, or all PVE gear could drop.  The randomness to the loot frustrates many players.  It also means that groups should attempt to bring as many different classes and specs as possible so that most loot can be used.
