Possible typo?

The titles are meant for general use (where Strength does come in handy) and carrying a backup melee weapon (which rely on Strength) is a good idea for Fighters anyway. It also makes sense because you'd expect the master of close range fighting to be strong too.

A lot of life skills (and not too many at that) add stats other than Dex as to draw in other types of players besides Archers into doing life skills, and make sense based on the skill. Do you honestly expect to become more nimble chopping wood or doing chemistry or botany?

What you say doesn't make sense does make perfect sense.

And let's face facts: DevCat is ran by a bunch of humans who can make mistakes. Why would they give a nonsensical stat boost to the Talent based around a combat type that is for a completely different stat intentionally?

They wouldn't. They made a mistake. They rectified it.
