The devil is in the details on this, which we don't have.  I've long lobbied for changes to cross-training skills.  Like most of the other issues I've lobbied for change to, this one seems to be the least obvious solution to the problem.  Linking un-related skills together, what?
Can't make sense of the idea even if it's meant to solve a long ignored problem in the game.
