Random Stats: Story vs Creativity vs Math

As I'm gearing up to try to run a game or two, I've been thinking of how to generate ability scores. For my tentative 2nd Edition Al-Qadim game, I've got the following penciled in:

Roll 4d6 and drop the lowest die in order for each ability score. If you are human, you may rearrange them in any order you choose. You must fit race and class minimums and maximums for any given score.

This gives us randomness while, at the same time allowing people to play the class they desire at the cost of an interesting race. I waffle over whether to somehow encourage a few other races by allowing them one ability swap to a "favored class" sort of thing: something like an elf may swap Intelligence with one other score, a dwarf may swap strength with one other score, a halfling may swap dexterity with one other score, etc. "Rare" races could be not allowed a swap so you either pick the race you want or the best class but not both. Less relevant for a game with a limited slate of races than an open-ended game like 4e which had a Mos Eisley cantina of races.

I like the idea of random ability scores, but the post third-edition math makes rolling potentially really bad. That is to say, a few high scores can be slightly unbalancing, whereas older editions didn't assume you'd have particularly high scores at all.

Now, I wouldn't encourage rolling abilities for anything third edition or later. The bonuses are just too important. One high stat can make a great OSR character, but you're not hindered by mediocre stats.

What's the benefit of randomness? I think, beyond some fetish for tradition and dice rolling, I think it forces a little creativity. We often let players make characters ahead of time, or else they have ideas of what they want to make before arriving at the table. But once you're stating at a 16 strength and 12 intelligence you've got a choice: Do I make the wizard I want who struggles with wizardry, or pick the fighter because I've got the stats for it? Because fewer things are based on stats in older versions of D&D, you can make a 12 intelligence wizard who is relatively functional. You cannot do that in modern editions of the game.

However. Some of the randomness may come at a price. Namely, it may be best to start with a coherent party rather than character concepts. And once the players decide they want to be crusaders fighting against demonic old gods and founding a new city to dedicated to their ideals... Those paladin-preventing scores could be rough. If I'm asking players to decide before they create characters what sort of alignment or ideals the party might have, that may limit some character options that randomness would encourage or possibly discourage.

I'm hoping my rule above has struck a reasonable balance. By allowing humans to swap scores around, it allows people to be the rarer classes of their choosing. It also will make demihumans less common: non-humans are more likely to have unexpected high and low ability scores for their class which or the player might opt for a class that fits the race better.

One possible problem I see, however, is that 2nd edition (like pretty much all editions) needs a healer. It may be beyond randomness in character creation though. If no one rolls well for wisdom or wants to be a priest, there's not many healing options. I'm hoping to alleviate this decision by including the Spells & Magic crusader and monk (revised as Dervish) alongside the more native Al-Qadim classes. I.e. more priest choices so one might be more appealing to players.

None of this, however, deals with the problems of a possible 5e game though. If you roll 4d6 drop the lowest the average character will have at least a 15 as their highest score and its reasonably likely to having between a 14 and 17 as their highest on either end of the probabillity curve. These numbers are high at low levels, but the cap at 20 probably helps. Most ability scores will end up 9-15 (within one standard deviation of the mean of 12.2), which is at least in a reasonable range for modern D&D. Maybe its not worth worrying about it and using the same rule will be fine. Or maybe the rule should only be by-the-book humans rather than variant humans. But here's the real problem: low scores aren't a huge deal in second edition, but in modern editions (including 13th Age) they are.

Low scores can be damning in modern editions. The fact that the 13th Age designers hadn't encountered characters with a negative constitution modifier before making the necromancer in 13 True Ways highlights this. Stats under 8 make for some really shitty characters. This is obviously mitigated by point-buy options, but rolling a 6 isn't going to be super uncommon.

The possible answer: Modify the rule above to allow humans to choose the standard array. This would ensure no PCs have crazy low stats, but doesn't prevent luck from giving someone three 17s, which are bumped up by the chosen race. I might just have to live with a little luck, I suppose, unless I want all the characters to include no randomness whatsoever. And I like how my rule encourages humans at any rate.

I suppose I could reduce the role of luck by changing the rolling method if there's a point buy backup for humans. 3d6 in order, or 3d6 twice in order might do. There's still a chance that luck will grant an exceptional character to one player while the others rely on a point buy.

One possible problem remains with randomness: The players decide on a mercenary party attempting to raid the tombs of old gods to find the wealth needed to found a new city and rule over it, yet one player rolls perfect paladin or monk stats. Maybe that's just a roleplaying or creativity challenge if the player really wants to play the character they rolled who doesn't quite fit the party. Or maybe the party needs to be designed at the same time as ability scores are rolled.

Ultimately, I still like my rule. Modulo it might need to be adapted for a specific version of the game and specific racial desiderata. Minimums or rearranging ought to prevent absolutely useless characters, and randomness can nicely constrain creativity. However, it means one does need to tread carefully with the party story perhaps.
