I remember rolling stats in TES: Arena and rerolling until I got the best spread possible. Rolling for stats doesn't make the game more interesting for me, it just makes character creation more tedious and lengthy. You have dice, in theory you could do some rolling and redistribute your points to be more in line with rolled stats, but in practice, Larian doesn't allow stats lower than 8 or higher than 15 (without bonuses). Rather than changing the system entirely, I'd rather they unlock the caps and let people play more creatively with point distribution if they want to. But I imagine that it is that it is the way it is to avoid letting true newbies create totally broken characters without understanding the consequences and/or to avoid "death by 0 stat" caused by debuffs that was mentioned in another thread.
