World of Warcraft Q&A

WorldofWar.de has published an interview with Blizzard's Chris Sigaty, in which the developer addresses several aspects of the MMORPG. Here's a snip about the upcoming hero classes:
Q: Will the hero classes be tested in the beta? What do we have to expect? Any concerns about new imbalances through this classes?

A: No, they will not be tested in beta, they will be patched into the game after it is shipped. The hero classes will be connected with the talents. You can achieve hero points and distribute them. There will probably be a forth tab in the talent menu for the hero class. The game is constantly under balancing issues so we will surely try to balance the hero classes out when they are available.
