So how about this... How about, instead of having a "simple" race which forces every Human character to be simple, instead having a Human race that is just as complex as the others, but then having an option for everyone no matter the race, to have +1 to all stats instead of all the racial benefits package?
That's a great idea. It also helps when you have truly different characters, like when a player wants cat folk and there is no time to make it up.
