The final day at Blizzcon is winding down and I made it back to my hotel to update you guys on the news. Not a ton of information to add to the pile today but I've been squirrelling away tidbits as much as I could. As you may have seen from my tweets I did not manage to get a good spot in the Q/A line and they ended the questions before I could speak. That said, there was not a professions developer on the panel and the answers they gave to other questions were a bit vague, so I'm not sure we would have gotten terribly detailed information from my queries.
Here's what I learned today:
The starter buildings for the Garrison will be a town hall, a mine, a farm and a fishing shack. You will use the town hall to interact with your followers and assign them tasks.
Small buildings include the Alchemy Lab, the Smithy, Enchanter's Study, Engineering Works and Scribe's Office.
Medium buildings include the Inn, Barn, Lumber Mill, Trading Post and Pet Stable
Large buildings include the Infirmary, Armory, Stable and Mage Tower
There will be Barracks and the barracks will allow you to get more followers.
Each building will have its own unique upgrade path.
The cost of a building on the sample screenshot was 10,000 gold!
Blueprints can be gotten via factions, questing, world drops and more. New tooltips will tell you the location for blueprints you don't have (much like the "not collected" pet lists).
After your garrison has been upgraded 3 times you'll be able to unlock a specialization. You may be able to change your specialization once per day (a cost may be associated with doing this).
All profession buildings can have followers
Your followers will be able to collect ore at your mine while you are offline.
New tiers of the garrison will offer more plots (for buildings). You fill all the current plots to upgrade to the next tier.
Missions will have difficulty ratings similar to quests (green, yellow, orange).
Your mine may have nodes inside that you can gather, in addition to followers who will gather for you.
Garrisons are unique per character and not an account wide feature, plans to support alts have not been fleshed out yet (WoW Q/A answer)
Garrisons will probably not allow you to make epic weapons from the Smithy but this aspect of garrisons has not really been planned out yet, they would like to balance it with players who are Blacksmiths. Current plans are to let players use garrisons to find recipes and do missions. No concrete plans on what types of recipes will be available this way.
The slots used for enchantments will be reduced but the number of enchants available per slot will increase.
There will be fewer gem sockets on gear but the gems will be more powerful. Meta gems are going away.
This is all I collected on Day 2, we'll see if any further information comes out in the aftermath!
