Until recently I was using this rolled array hybrid:
Roll 14d6. Drop the two lowest rolls. Add two rolled numbers to one number from the following array: 6 5 5 4 4 3. Each number can only be used once. Arrange as desired.
I was allowing the players to reroll if their total dice added up to 42 or less.
However, this lead to PC stats being slightly higher than I intended, so I came up with the following instead:
All of the methods from the PHB are allowed, as is the above rolled array hybrid (and a few other hybrid variants). If, after rolling, the players don't like their stats they may choose to use either this array (16, 14, 13, 12, 10, 6) or PHB point-buy. This way, rather than trending high they will trend towards the average with high rolls being unusual and exceptional (which is what I'm aiming for).
