|The Storehouse doesn't actually make resources but |
you could pretend to store them there. Or something.
So when I spent my 2000 resources, I did so with a little niggling worry in the back of my head: these resources had been mostly found using quest rewards...ones that I'd never be able to collect again. These were non-renewable resources, which if we have learned anything from our dependence on fossil fuels, should teach us that one should never build an economy on that.
Blizzard has done a pretty arcane job of giving us ways to generate resources. There are some "easy" ways to do this, but those are almost exclusively non-renewable. Which is to say, you'll get that haul once and then never again. There are some renewable sources of garrison resources but they need some set up work to become effective. And then there are other sources that will require your constant attention.
