Something that was common in 2e was a swap feat, something that let you use one skill or attribute for something else. I've seen it a few times in 3e, but not in a big way. Something like "Nimble - Use Agility instead of Strength for Athletics." Are those allowed now? Should they be, if they make sense, or is it better to keep attributes for their linked skills and nothing more?
I've done a Fascinate with Expert: Science as the character goes on and on about science, putting people in a daze.
