We're here at E3 and, although not blown away by any major announcements from Blizzard, did get a chance to check out a preview of the new 10-man Zul'Aman outdoor instance in Ghostlands. It's going to be a more casual dungeon than Karazhan, ideally doable in a few hours' time investment, with six bosses and no attunement required. There will be quests included as part of the story line, with at least one rescue mission per avatar boss that will have a time-dependent element similar to the Baron Run mechanic in Stratholme, with better rewards offered for quicker completion. The six bosses include bear, dragonhawk and lynx avatars, a "god of evil," a witch doctor, and the final troll boss Zul'jin. Like Hakkar in Zul'Gurub, Zul'jin has a spiritual connection with the other boss avatars and is able to draw upon their ghostly spirits in order to change his shape and assume some of their powers and abilities. All the bosses and the trash mobs (which will be primarily forest trolls) will be social and able to call for help from additional mobs -- surely good for a few wipes whilst learning the encounters.
Blizzard offered a few other small bits of news: voice chat and guild banks will be coming in minor patches before the big Zul'Aman patch is released. Voice chat will include a feature that automagically lowers the game volume when players are talking, and onscreen interface indicators to help keep track of who is talking at any given time. Guild banks will be endowed with some sort of permission system enabling guild masters to give access to specific items to some guild members and not others.
Unfortunately, Starcraft 2 was not yet playable, but we'll be looking forward to that and far more megaton news to be forthcoming at Blizzcon -- it's clear this press conference was merely a teaser.
