In the last two patches, Silver Tongue rose in price from 30 gp to 100 gp. I find that to be pretty tough, especially in the early-mid game when my economy is weak.
I started thinking (I know, dangerous, right ?!? ) what if the player wanted to use some fame points to offset some of the gold cost? This would let a player use fame at a rate of 10 gildar for one fame. So a Sov hard up for cash might use fame and delay their next hero, but get the turncoat unit they need to win the battle today.
And/Or what if the fee was changed to a flat 20 gildar per figure in the unit? Thus the cost of bribing scales with unit size. So I pay 60 gildar for Panca Archers, and 100 gildar for a 5 man unit of Tradesteel Riders (good job on all of the units, Kongdej!).
A similar thing could also be done with Bandit Lord, but I am going to post that in the existing thread.
