I'm not sure if the requirements are a simple "you need X Intimidate to succeed, no less", or if it's a "you need X intimidate to have a 100% chance to succeed. Less will reduce your chance to succeed a lot."
The idea of being told exactly what you need up front to succeed does not appeal to me. How would someone know? Also, that discourages roleplaying and trying to figure out the right response, and makes it into a numbers game.
