OK, making up a character and took the following Origin Path:
Fortress World [provides Hatred]
In Service to the Throne (Tithed)
Crusade (Call to War) [provides Hatred]
The Hand of War* [provides Hatred]
Devotion (Duty)
Missionary
* Each character is allowed "one free choice" that is not limited by the choices above and below it .
This gives us a character with the back ground of having been raised on a highly militant world braced to resist a nearby Ork presence. So we take Hatred (Orks) as the selection from Fortress World. The character in question wishes for the Crusade (Call to War) and The Hand of War to also reflect a past battling against Orks instead of a spread of opponents.
There are rules for getting a redundant Talent, both generally and when taking the xp-based options from Into the Storm. I've heard some say that you can't voluntarily take a redundant Talent (or Skill) in order to swap for Talented (Choose One) if there is another option that could be taken, but I don't see a rule that supports this. If there is somewhere stating that you can't make a redundant selection for the purpose of swapping out the choice for Talented (Choose One) or a +10 Skill, please point it out.
What I'm considering is taking Hatred (Orks) with Fortress World, Talented (Medicae) in place of the redundant Hatred (Orks) from The Hand of War, and a 50 xp reduction in the cost of Crusade (Call to War) instead of another redundant Hatred (Orks). Do this seem reasonable? Is this per the letter of the rules?
