Still doable.No thanks. Default = roll.
The array is mostly a measure to set the tone. Essentially a typical statblock.
But a player can easily use the 8+2d4 dice instead.
The array gives every player a 16, 15, and 14, in other words, a good score in every important ability. Even if an other player at the same table rolls straight 16s for all six abilities, the character wont be that much more powerful than the default array.
So the default can be the array − and at the same time − any player who chooses to can roll.
