We've only played Belfort once, but the random guilds we pulled include the promo pack's contractor's guild.
We all thought it seems really overpowered, especially once someone buys it. Three resources for one worker!
Is it just us?
How much wood or stone do you get from the guilds that give those resources 4, right? And 3 gold from the Banker's Guild?
I don't see how this is out of line with those...
