I was just reading the "Thugs & Angels" thread on the General forum, recalling some characters from my old stat-rolling days, and thinking... does anyone else feel 4E point buy should have an option to take stats below 8, and multiple stats below 10?
I recognize that this increases the abuse potential of dump stats, and I'd be fine with sharply diminishing returns--say, one-half point buy for each point you reduce your stats below the standard minimums. (So, if you take your lowest stat down to 7 and your second-lowest to 9, you get a total of one more point to play with on your remaining stats.) That would discourage casually dumping your unused stats to 3, while still providing some compensation for an extra-low stat. It would also offer a way to "stretch" your good stats just a little bit farther, if there's a feat you really want but don't quite qualify for.
What do you think?
The way I see it, once you get to negative stat modifiers, further reducing an already poor stat is
not the same rate of return on consequences as the benefits you get by increasing a primary/secondary/"good" stat even further.
That is to say, once you have your "dump stat" the penalty from changing it from a -1 to -4 is not equal to the benefit you gain by taking a primary (or secondary/"good") stat and increasing it from +3 to +4 or whatever. Plain and simple because the dump stat will get used a whole heck of a lot less by virtue of it being poor for the PC. (i.e. if it's intelligence, you aren't the one in the party who is going to try all the knowledge checks so you'll never use it unless you have to without another option, or if it's Charisma, you'll never volunteer to be the "face man" for the party; conversely, if you are good at intelligence (or charisma), you'll volunteer to make knowledge or other int-related checks (or be the face man); and your attacks, damages, rider effects, defenses are going to get based on your 'good' stats resulting in exponentially more uses of your good stat modifier than the poor stat modifier)
So if someone wanted an even lower ability score, I'd let him/her (costing the same as a 8 score via point buy, regardless of how much lower the score actually was), and I would
not compensate by increasing a good ability score upwards. Instead, I'd let the PC use it as a basis for roleplaying and therefore it would come out in story (which should be its own reward if the player is doing it for roleplay reasons in the first place).
Having said that, there is always room for roleplay as being worse in something than the stat would define. i.e. you could have an 8 int but still roleplay that you have a terrible memory, etc. thus, keeping your stat but working in the flavor via RP and in-game interactions.
Of course, YMMV.
