In terms of Factions itself, we're looking at a whole new entry point for the gamer. If you buy it in the shops, you can play its campaign by itself and enter the PvP duels. If you don't buy it, you can still play everything you already have in the original Guild Wars Prohecies pack. And if you buy both, you get a couple of extra-slots for new characters and can transfer your experienced characters from the old world to the new once a certain point is reached.

The two biggest additions are the two new classes - the Assassin and the Ritualist, both of whom are perfectly dual-classable with the original six archetypes. The Assassin is a swift-damage dealer-type, whose main offensive abilities are linked to the ability to chain attacks together. An Opening attack allows you to apply your off-handed attack abilities next and that in turn allows you to finish off with the dual-strike abilities (And then onto certain Elite skills). There's also an array of ninja-styled hit-and-run abilities, which leads them to be favoured by (say) anyone who likes to play Thief a lot. Not that I know any of them.
