The offshoot of getting your desire would be getting 10 good negotiations in GBG like you currently do in GE.I do think that negotiating in Battlegrounds should have an extra turn option, like the Guild Expedition does. When there are 6 possible goods, it is very unlikely that one can successfully negotiate without spending Diamonds or repeating the negotiation 3 or more times, until the solution has less possible number of goods. Oh, btw, when a negotiation fails, and the pop-up comes up about the Diamonds, it totally blocks the player's view of the negotiation, and a player can't really evaluate whether paying the Diamonds is a good option.
You sure you want that?
I sure don't, since I can do 6 good negotiations without a tavern boost, but I can't do 10 good negotiations without one, and my tavern boost slot is normally already taken by a 24 hour attack boost.
