A player recently pointed out to me something very unfortunate. He has announced that upon completing his current career, he plans to never finish another career. Instead, he will pick a mostly-compatible career with useful Primary Characteristics and 2 Fortune Advances. He'll adopt that career, spend 2 XP on Fortune dice, then change careers. Again and again. At first, I thought this was crazy talk. Then I ran the math.
Completing a career and transitioning to a new one costs 10 to 13 XP. For whatever specific die pool you feel is most important to your character, your time in that career will probably gain you 1 Yellow die and 1 to 3 White dice. That's a skill, a specialization, and up to 2 Fortune Dice.
The cheesier approach, of cherry-picking just the fortune dice, and then transitioning out of a career will cost you 2 to 6 XP. If you choose really uncompatible careers, you're looking at a mere 4 White dice for the 12 XP or so that got the career completist 1 Yellow and 3 White, so that's suboptimal. But if you're Human and the careers all have 2 or more keywords in common, those 12 XP could score you 8 to 12 Fortune Dice!
I haven't looked closely at the giant stack of careers since he pointed this out, so I may very well be missing something here. It's possible that there just aren't enough careers with Primary Characteristic and Keyword overlap and the 2 Fortune advances needed to make this work. Dear god, I hope there isn't, but I suspect that stack of careers is big enough for this to be viable for at least a rank or two.
Has anyone encountered this loophole before? It seems abusive to me, not in the spirit of the game, yet I see nothing in the rules that would stop it. It makes mechanical and mathematical sense, but boy does it leave a bitter taste in my mouth. I mean this really is the best way to improve your dice pool in a focused area, but it's just so damn cheesy. Especially when you get to Rank 4 and are already maxed out on Skill dice anyway, and don't really want any more Stance Pieces or Talents, there's a strong motivation to just cycle through careers cherry-picking white dice as fast as possible. When the PCs are 4th Rank, I'd rather they be taking the flavorful high-end careers like Knight of the Inner Circle, not inexplicably dabbling in Boatman and Thug for 2 sessions a piece to score dice. There's definitely a disconnect between what makes sense in-character and what makes for the strongest character.
My kneejerk reaction to this is to house-rule that career completion is mandatory, so as to just nip this in the bud. Any thoughts? Are there any compelling arguments for keeping things as written instead of house-ruling over this exploit?
