Ehh.. I think I sill like the idea of a base difficulty.. I think I'll be keeping it at 3+, maybe +2, and/or changing on a case by case basis, but I'm to be honest, not entirely sure yet...
Its just to me, when I think of it, I have to try to see a balance between the mechanics and the thematics.. Someone with a Discipline of Fair +1, honestly isn't going to have much of a chance to quite and still their mind. They might have an easier time attempting to concentrate on the task at hand, true, but even that would have some form of difficulty.
I guess at the moment, I'm arguing more for a variable difficulty, that at very least, isn't Zero... Because in all honesty, if its so easy to do, you might as well not even roll on it, its easy enough to do, that it probably wouldn't be able to provide an advantage to you anyway...
