Changes to Culling of Stratholme that allow players to skip past the initial story elements will be in a future patch. What seems simple ended up taking a bit of time to implement, and will take just as long if not longer for QA to fully test. I wanted to make sure the quests are still able to be completed, and nothing broke in some rare but significant boundary cases.

Along with the huge change to allow skipping, there's other smaller changes. I lowered the delay after the first boss dies until the undead waves start again. Arthas no longer physically runs from the front to the inn, he just teleports there. Arthas runs to the bookshelf instead of walking.
