Hmm, I think it makes people more willing to go for opportunities they normally know they would fail otherwise.But why?
If you haven't done the work to gain the required point, why should you gain it?
I guess, if you look at in RL, as you gain more skill you would have better chance of success, so it's fair, in that regard.
But still, you're not getting a job that wants people who speak 100% fluent French, if you only speak 70-80% of the language.
Also, it would give the MP stats a better meaning as know you don't fail it 100% of the time but have a chance to succeed.
Not saying I am adding it or not. Just trying to think of all the possibilities.
