If it is exceedingly difficult to find (or craft) a GG item, thats good.
I don’t want tempering/masterworking to become what we currently have: Get a good item, upgrade it x 5, and done. So everyone is running around with x5 upgraded items.
It would be great if most people might have one or two really good items and the rest just be ‘good’. You dont want everyone in the game running around in stacked BIS GG items. That defeats the point of loot hunting in a game.
