Guild Wars 2

Is it more gold efficient to buy the destroyer cores and craft the lodestones with the wines or just buy the lodestones outright?

I have been thinking about this same thing for a while now. If you put a buy order in for the cores and get them under 50s, then yes it is cheaper to craft the lodestones then it is to buy them. The main thing is not to pay to much for the cores. If you have patience to do the buy order you can make it worth it to do it that way.
