Honestly, I sometimes wonder if it's really necessary for characters to be extremely weak in some areas for them to be extremely strong in others. I get that we generally don't want perfect protagonist for any work of fiction or a game. But the system as it stands now really does encourage people to ignore the attributes that don't directly correspond with the effectiveness of their class. I'm playing a Druid in a campaign right now with a 9 Strength. Does that really make any sense? Most adventurers are young (for their race), physically fit individuals in the prime of their lives. They're physically fit because their occupation demands it. Even a Wizard needs to run from time-to-time. And yet it's completely normal to have a Fighter with a 9-10 Intelligence, a Wizard with a 9 Strength, etc., etc.
