I have 3 copies. I need to see which ones I have now. I like either of the bonuses for the profession. I can see both making sense, but the duelist prefers only honorable, fair combat so I can see arguments can be mad against either of the bonuses as well. Quite the conundrum.
I wonder, armed with this knowledge, will GMs inform the player of this? Offer them to choose one or the other bonus, or deny one or the other bonus. Personally, I think I would allow the players to pick the bonus that better fits the archetype they have envisioned for their PC. RM is nothing if not about having options!
