It doesn't matter too much if your buying a scout and doing some power training with them when the scout comes with balanced stats because at least you assign the skill points earned in the area you want, I tend to find that for defenders I go 110/100/105 for a 105 quality player. A Striker I'd go 100/110/105 for a 105 quality player, I don't like too much imbalance, it seems to affect their all around game.
