Why do splints, broken legs and the associated talents exist? The only way you're gonna get a broken leg is by getting run over by your friend which happens less often than the system is worth (and is annoying as fuck) or VDMed, and the latter only puts the victims of VDM at an even more disadvantage.
You also have to waste a talent point on having your legs less likely to be broken to be able to wake up in hospital, and the talent spams you with "Someone less hardy could have been seriously injured!" even after your legs are broken.
