You beat me to posting this, but, they already have something like this planned.
If you read the races section, at the very bottom of a selected race, they will state the starting strength, agility, etc. points that they will eventually have to raise themselves. Now, because we can create our character\'s past actions/events, those stats will vary. Depending on what happened then, and what happened as they played, their stats should go as high as what they had trained it to. Now, it is a bit confusing. This is our current system, but I agree, a Kran would be much stronger than a Lemur, AT THE BEGINNING, but if that Lemur trained him or her self to be stronger than a Kran, that is what they should be. Also, there should be limits to stats, a Lemur should only be able to excel so far in strength, and should be able to go further in intelligence. A Kran would be the exact opposite.
