One of the appeals of previous editions of WHFRP is the concept of characters starting out as the low man on the totem pole; gutter trash trying just to survive in a very unforgiving world. IMHO, 3e makes the PCs a bit more heroic and less the underdog. One thing I would love to see in addressing this feeling is the introduction of a "flaws" mechanic, such as is used in games like GURPS, Ars Magica, and even the Decipher LOTR RPG. It seems that something detailing physical, personal, and background flaws & problems would be a natural fit for WHFRP.
I can just imagine the gimpy-leg-in-bad-weather card, the black-sheep-of-the-family card, the gag-inducing-bad-breath card, the can't-help-but-insult-royalty card... and so on.
Thoughts?
