So if I'm LMA and fighting in EMA it'll produce LMA goods that my guild cannot use...really great help. Why not allowing us to choose the era, or even better, finally get us a way to trade with goods out of treasury.
Those goods can be exchanged, but all goods that we get that way must stay in treasury, and you dont't have to make it 2:1, but that 10:1 in the same age is ridiculous, set a likely price (2:1 in the same era, 4:1 one era up or 1:1 one era down).
That way nobody will use that as steady market tool, but it'll give us some reason to build Observatory...Deff alone is not making me using 3x3 space and wasting all those FPs...
