Unfortunately I was unable to watch some of the WoW panels that happened today, the DirectTV broadcast is only showing one of them. Luckily Blizzard has been posting recaps on their web site for those who aren't in Anaheim. I just went through the Systems panel recap and I see that there's some information relevant to crafters. It looks as though professions will be a part of the guild advancement system. Within this system are some pretty key features that I think will help solve some long-standing problems with guild crafting.
Guild advancement is basically an achievement/leveling system for guilds. It looks like guild members will be able to earn experience for their guild through such activities as leveling, boss kills, PVP, leveling and profession ranks. In return the guild will be able to unlock access to a number of perks for its members including guild recipes, special reagent vendors, vanity pets and heirloom items.
The way that it's currently planned to work is that a guild would use some form of guild currency to buy new recipes that would be unlocked for everyone in the guild. Guilds would also have the ability to create heirloom items that would be available to players within the guild. It looks like guild vendors would stock reagents that could be purchased by guild members as well as unlock guild-specific versions of crafted items that could potentially have fewer reagents.
There is also plans for a guild news feed, which is mentioned in conjunction with profession information being made available to all guild members. It's unclear if this information is shared via the news feed or some other mechanic, the interface graphic has no indication either :(
Personally, I think making tradeskill information available on a guild-wide basis is long overdue. So "thank you" to whoever decided to finally implement this. It has been a huge pain to coordinate crafting between guild members, compounded by the fact that some folks just aren't on at the same time. I know for awhile during Burning Crusade I actually kept a notebook list of folks in my guild who won epic loot recipes, so I'd be able to remember who to pester to get items made. This is a pretty sad way to track guild crafters, when all the data is in the game and just needed a UI so players could use it.
I also like the idea of guild-owned recipes, it seems like a much nicer way to handle the raid drop recipe. At least I hope that's the implementation they're planning, I always thought it sucked that the one dude who happened to be in the raid when the recipe dropped was the one who got the recipe. How often does it happen that this is the guy who's not a core raider? Or even worse, leaves a month later and takes the epic recipe with him. If they do decide to have guild-based recipes, they need to make sure that players lose the recipe when they leave the guild. We wouldn't want to encourage guild hopping, now would we? <no, we wouldn't>. I think stuff like this would also strengthen guild loyalties if players knew that they'd be losing their heirlooms and guild recipes when they left.
There's a lot of neato stuff in this systems panel that's not related to tradeskills. If you want to read the whole article for yourself, you can find it at the Blizzcon web site.
