World of Warcraft's next expansion is going to feature housing. Not just housing, in fact, since Garrisons are sprawling complexes under your direct control. So you know you need to figure out how you can afford it. You've been farming diligently, even resorting to shaking down repair vendors for gold, although that one hasn't worked out so well. But as it turns out, you don't need to worry. According to a tweet by Senior Game Designer Jeremy Feasel, Garrisons won't cost you gold.
Feasel specifies in the tweet that Garrisons will use their own resource, stating that more information about what that resource is and how it can be gathered will be available soon. So you can rest easy knowing that your hard-won gold won't be needed to build your fortress. Or you can rest despondent that all of your gold won't buy you a nicer place. Either one, really.
