as a second option... maybe have NPC's react to rolls they witness as well. for instance
Player emotes [intimidate] in line of sight of an NPC, said NPC makes a secret counter roll... and either walks away or possibly gets in the PC's face...
I could see people's roleplay changing in the Ladies Rest if everytime they start threatening another, Radu starts cracking skulls.
Wouldn't have to be a immediate change, maybe he would warn them once or twice before kicking their arse.
