Why? Because you just kept rolling until you hit a 96? Because that's what I've done for 25 years, and so did everyone else.
In classic BG, that was all fine, becasue the only roleplay element there was, was 'Yes, for honor!' 'Okay, but for gold' and 'Fine, but I'll kill your cat after'
This game is entirely different, where having strengths and weaknesses matter.
*nobody* will roll and role-play, everyone will keep rolling until they max everything out and roll-play. They might as well give you 18 in every stat, thereby skipping the Stat allocation entirely.
