Re: I'm curious, why is Dex still more expensive than other characteristics?
No rolls are really necessary. In fact' date=' in a lot of cases, going outside and tossing a frisbee or baseball around might actually be more preferable. Constitution's primary function was to prevent STUN effects. Which is why the three things you listed are Secondary or Figured.
Quite regularly if the concept didn't call for a high CON score.
Nothing personal, but I agree with Bigby on this. Sounds like it would suck unless the intent is a really simplistic game.
