Powers and Pawns introduced a load of talents for Swordmasters and Suk doctors. Duncan Idaho and Wellington Yueh were given statblocks (in the core rulebook) before these came out. In particular, that means Duncan looks a bit weak compared to what a Swordmaster looks like with the new talents.
If you were to redo Yueh and Idaho’s talent lists, what would you give them?
Yueh is a major character, and not a newly created player character. 4+ talents seemed appropriate for someone of his experience. They gave Paul 5+ talents. 3 is not a hard limit for any character.
