Try (3d12, pick the middle one) + 5
Not a Maths buff here (at all). Just wondered. Thanks.
Is there anything in auto-starting with a 16 in your main stat (after racial addons) and totally randomising the rest?
I personally don't like rerolls or redos, unless it's forced rolling. I've offered either rolling or point buy as an option, but if you roll you're stuck with it. This represents the risk of getting higher stats (statistically likely), but with a descent chance of being worse than point buy. Eventually I relented (my players hate point buy), and now allow a rolled character to default to standard array, which is just worse than point buy.The last time I was a player, that DM made us all roll 4d6 drop lowest twice and choose, but there were no rerolls or redos period. That guy REALLY believes in the random.
Variable ability scores within the party was a significant issue in 3E (and probably 4E too), but it's not quite as bad in 5E. With bounded accuracy a character can still contribute, if at a lower capacity (I've done it myself). Of course, if you have hyper competitive players, this is a serious problem, regardless of edition. I was a player in a campaign that died in session 0 because one player rolled way better than another player, causing a massive argument.I've used point buy since 3E. Why? I hate the swing factor. Not for PCs, in general -- I can adapt to any group power curve. It's because it almost always results in one player having super high stats, with another having super low stats. Sure, you can set lower bounds and eyeball rerolls, but what's the right level of "cheat"? Also, if the PCs have a possibility of coming up 18, 18, 17, 16, 15, 14, shouldn't there also be a consummate risk? Granted, being simply "average" when another PC has the above stats is punishment enough. It's even worse when you have to play the "standard array" powered character while Superman came on a reroll after that player got a first roll bad enough to be considered unplayable, especially if the chump was about the same number of bonuses below your standard character as your standard character is below the new one.
