Yeah that seems to be the consensus so far is a grouped random roll, i will think it over thank you everyone for the feedback!What about Rolled Array? One single set of rolled scores that everyone at the table uses, random but fair.
Although I personally do prefer the security of point buy to the chance of random rolls.
I still prefer a choice of several arrays, where the players can assign the numbers as they choose, allowing for a little variation while still keeping everyone at the same relative range of ability scores.
Edit: Oooor, I could include both options, with a choice of arrays or random rolls per player, and then an additional option for pooled random rolls.
