Re: Where do your chars put their XPs?
Typically, from the last time I ran FH, players tend to improve their experience in improving their character's schtick, and tend not to diversify much. This works for me on the basis that I like PCs being distinctive, having their own specialties and schticks, and minimal toe-stepping-onning.
The swashbuckler worked on more swashbuckly things ... fencing martial arts, levels, Leaping w/Acrobatics check, increasing Acrobatics, Climbing and such
The barbarian worked on his toughness and ability to take damage and shrug things off.
The crossbowman worked on his accuracy and developed trick-shot powers.
The exception was the whip-wielding duelist, who opted to pick up some ice- and warrior-magery tricks.
