Keep in mind what attributes really represent as well. It's much easier to focus your efforts on a particular task to improve skill, but to significantly improve all the multiple facets represented by a raw statistic takes tremendous effort.
STRength isn't just lifting weights: it's endurance (swimming), it's toning, and it's the simplest.
BODy is health, and bulk, and resilience and pain resistance.
AGIlity and REAction, it's incredibly hard to raise those base stats.
And how do you fundamentally improve your CHArisma?
Just a thought.
While I agree with you that attributes can represent well, I have to disagree with your examples. People decide to change these fundamental qualities every day, and do.
Strength: People get stronger every day just by going to the gym. They measure themselves objectively by their ability to do more reps and lift increased weight. Training programs these days cover toning, bulking, core work, balance, yadda yadda. Honestly I can't think of a stat it should be easier to raise, given time. Better yet, the game gives us a rough yardstick for strength in terms of deadlift capacity. It's definitely got a bit of hero physics built in, but the objective measurement is there.
Body: Same as above. While the stat does represent pain resistance, I think we can all agree that limiting purchasing Body for want of an efficient pain-resistance training system is silly. It's also logical to argue that people who suffer through muscle-rending workouts are, in effect, training themselves to resist pain. Cardio work means their lung capacity is increased, and all sorts of studies support the idea that people in good physical shape fight off diseases better. They can always go on a strict diet and add in vitamin supplements for the health part.
Agility and Reaction: Easily increased by video games and playing sports. Occupational therapists use video games for just that sort of thing. Martial arts can also train both Reaction and Agility, as can gymnastics.
Charisma: Start taking better care of your appearance, read books on social interaction/sales/psychology, spend a lot of time in social situations getting to know the ins and outs of meeting people and growing relationships. Study cultural and racial etiquette so you know what not to do. Play poker and read books on bluffing to get better at lying. Everybody knows at least one person who isn't attractive at all that has loads of friends and dates. Personally I know several. There is an entire industry built around improving relationship building/networking/sales skills. Anyone who is in sales or sarges (same difference, I guess) will tell you that developing self confidence will get you about 50% of the way to persuading anyone.
Now, of course this sort of training only takes you so far. However, the system uses Aptitude to represent true raw talent. It's logical within the rules to say given time people can increase all of their attributes at least a little. It might take several years to earn that 5th point of Charisma, but if you put in the karma, the time, and the RP, it's yours.
As for the increased costs, I used to play a lot of WW so the cost doesn't bother me. It might make the pools a little smaller, but most of the threats in SR are using the rule, too.
If the BP costs aren't changed, then it rewards players for loading up on attributes at start and rounding out with skills later. Some games might like the image of starting Runners as talented but relatively untrained folk. Others might not enjoy the ramifications for character diversity. I would be one of the latter, simply because I want flexibility at chargen, and for me that means the rules need to not push me in a certain direction.
Kgen sidesteps that particular issue neatly. However, it will only increase the incentive to play races with large stat bonuses in Kgen. Even if they change it to make people pay for race, the costs will still out-weigh the benefits. Poor humans.
