Many of us have already started successful survival worlds and ventured to the Nether before the snapshot. So how will we get our quartz, which is supposedly a very important redstone component? Why, let villagers trade it! I'd say one emerald for 2-4 quartz, which is the same price as redstone. What do you think?
The point of adding quartz was to provide an incentive for nether exploration. It kinda defeats the purpose to find it sold by villagers, unless it was a Super Rare trade, like saddles or something.
