ur characters will now have amazing stats, very much overpowered in my opinion, a char. in 3rd ed. will have maybe 1 stat of 18, 2 max, otherwise all other will be very low. But the two stats at 18 will be worth much much more than 2 stats at 18 in BG2 for example.
or maybe i'll explain it like this: a stat of 18 here is like maybe 22-23 in bg2, sort of...i'm not much for explaing today, sorry
