Thalandar, I'm with you, I just forget that rule half the time.
What everyone here is griping about is the idea of letting people get bonus BP by purchasing traits that force additional composure checks and then buying some (relatively) cheap 'ware that completely circumvents the quality.
My players are liable to be irritated with me, because I plan on doing a better job of remembering those composure rolls (although, as they get more experienced, you're supposed to stop asking as often). Also, if I were the player, I'd be less likely to keep playing if every time my character took a wound or saw a gruesome site, he had a chance of locking up and being useless for a GM-specified amount of time. It kind of takes the whole "fun game" part out of Shadowrun if you overdo that sort of thing. So, yay, another balancing act.
