So I noticed that in each of the guild storages, Member, Veteran, and Officer, there is a catagory for Minerals. However, it does not display Minerals in your own arsenal so that you could actually deposit minerals.... inevitably making the guild storage's mineral count stay at 0.
Now we know minerals can't be traded... so what's the purpose of having a place for it in the storage? Obviosuly guilds could use it to influence the gates, but how are guilds supposed to do that if they can't even put minerals there?
Unless of course there's some larger plot here that we don't know about.
AHA, I bet that is where the Lab comes in, HOPEFULLY
