There's a lot of historical characters having base stats of near 10 as well, lots of them have 8 in some of the stats. The thing is that some of them have traits that gain a bonus to those stats and some have traits giving bonuses to other stats not really that high. When you have a high base stat and have traits added on top of that he/she will be like an übermench, some historical characters got this as well. You as player has the opportunity to affect this process and you'll be able to create those spearheaded characters if you'd like.
