Have you ever seen RotW's Halfling Rogue? At 1st level, your ranged sneak attack is +1d6 and your melee sneak attack is +0. At 20th level, your ranged sneak attack is +10d6 and your melee sneak attack is +9d6. I'm pretty sure they meant for ranged to be +2d6 and melee to be +0, and then at 20th level for ranged to be +11d6 and melee to be +9d6.

Oh, and the entire mechanics for Jump and Carrying Capacities bother me.
According to the Carrying Capacities chart my Strength is between 16 and 20.
I have made DC 32 jumps and can reproduce the feat.
