I'm just not a fan of randomness in character gen at all.* Randomness comes later once the character is making choices and testing against skills and characteristics. Even then, Infamy allows a bit of an override against too much randomness. I prefer to see character gen as a 'safe spot' so the character can be built the way the player envisions them - at least at the outset, because the course of the game will likely force the character to adjust course sooner or later.

* FWIW, I even removed the random '+1d5' from the starting Wounds calculation and just replaced it with '+3' because of my dislike randomness in character generation.

@HappyDaze:  Thanks for the House Rule; our group has decided to use it for character creation.

Glad to hear it. If you're willing, throw a few of the combinations your players come up with (of both selected mechanical bonuses/penalties and what fluffy failings you've tied them to) on here to show some examples.

I'm not the GM, but I'll ask the group.  At the very least, I'll put mine up here when I figure out what I'm going to do.

Here's what I've come up with...

Pride: Grace: +5 Agility, -3 toughness.   (no need to suck it up when you never get hit)

Regret: +3 BS, -5 WS, -3 WP , Opponents are +10 to initmidate (Once bitten, twice shy: poor choices in the past make him indecisive when pressured. Dislikes direct confrontation and is easily bullied)

Legacy: +5 Int, +3 fellowship:  to represent long term planning and manipulation

Your totals are a bit off. Your values amount to 6 positives and 5 negatives. Changing one of the -3 values to a -5 will balance it out.

Here's the set for the most recent character I've built with this system, a CSM Chosen:

Pride: Martial Prowess (+5 Weapon Skill, +5 Strength)

Disgrace: Hubris (-5 Intelligence, -5 Perception)

Motivation: Violence (+5 Willpower, -5 Fellowship)
