I had an interesting thought not so long ago, which I wanted to share with developers and other TSO players.
I think it would be handy to have new kind of specialist like the ones buffing buildings around.
I mean nobody likes losing gold ore, especially on lower levels when gold mines are quite expensive to build.
Guild members not always can buff your prod chains, so you cant get away for long, when you running your XBowsmiths or other advanced/expert chains.
So with this new specialist you could assign sandwhiches and other buffs according to the building so when the buff ends new will be delivered ASAP
Also he could turn off production chains of selected type if buffs are out, so you could save your resources.
It could be available for gems from black market or for coins from tavern.
