Fearless Curiosity Feat Chain. Is it worth it?

[Discomancer]

Just looking over the ARG and noticed the Fearless Curiosity feat and it's subsequent, save-stacking feats (Intimidating Confidence and Dauntless Destiny). They seem interesting and useful, but that would be dependent upon how many emotion-effecting spells you are subject to, I suppose.

Still the other benefits aren't horrible. What are your thoughts?

As an aside: What about your feelings on the Surge of Success feat?

[Umbranus]

The feat chain looks interesting but it would have to be a rather special build, needing a lot of feats to be effective and at least some charisma.

The surge of success seems to be the perfect feat for a scimitar magus.
Many crits and every little to hit bonus helps.
