Phobias is an excellent suggestion Amber mentioned.

Overall, I don't think it would be a good idea to introduce many more 'strictly or situationally' positive traits for fear of them being grossly overrepresented. We have Cursed blood becoming a staple, divine eyes being included to many, many human's kits due to it's output. If unique or otherwise interesting traits get added, and they offer a significant enough benefit, they will be included on every single PvP build that can support it, and the only counterbalance would be to have too few trait points or too many options to utilise; effectively power scaling. If they are included, you pretty much would need to keep them away from all the cool lore implications as to not water down the identity. It's not the direction I think an RP game should go down with a mix-and-match of min-maxed traits and talents but hey, if it happens I wont particularly care.

Negative traits will increase variety at the cost of viability, whereas positive traits will do vice versa.
