WoW - Interview @ Eurogamer
Eurogamer talks to Jeff Kaplan about Wrath of the Lich King and what Blizzard learned from The Burning Crusade.
Eurogamer: There were some flaws in The Burning Crusade, such as the difficulty of accessing certain instances and other elements which caused concern for hardcore players. What did you learn from that?
Jeff Kaplan: I fully agree with you, we did learn many lessons from The Burning Crusade. We've already fixed the access issue with recent updates. I can't tell you a lot about the progression system in Wrath of the Lich King, but we're exploring new paths to make this add-on accessible to everyone.
For example, we could imagine some open content for a server rather than for a specific guild, like we did with Ahn'Qiraj. We could even push this basic concept a little further. You could also imagine a system which would allow you to grant access to all your characters once you've unlocked it with one of them. It's a very important matter for us; we don't want to remake what I personally consider a mistake in the Burning Crusade.
