With the introduction of Factions and the addition of the Assassin and the Ritualist, will changes be made to existing skills to "make room & balance" for the new professions or have you found balance without having to make changes to what has already been released?

We will not be substantially changing existing skills in order to add the Assassin and Ritualist to the character choices. At one point, I wondered about that, as well, and considered whether we might decide to shift even a whole attribute tree to a new profession. However, that's really not in the cards, nor is it necessary. The Ritualist and the Assassin compliment the core professions, and yet their skills and spells are uniquely their own. That’s not to say we won’t continuously examine the game for any imbalances, and adjustment accordingly. And naturally we will engage in the refreshing process that rebalances and skill tweaks and adjustments bring to the PvP scene, in particular. But major shifts to accommodate these new professions have not been designed.
