Do these abilities really need a 24 hour wait period to reset? I don't believe they do. Even the 1-hour reset time after the quarry is killed seems to strain credulity. What is the rationale behind this reset time other than arbitrary "game balance"? (I use the term in quotes because I don't think there is any game balance issue with removing the reset time.)
On another note, if the ranger kills his quarry he can declare another one in 1 hour, but what if he captures his quarry? I should think capturing should at least allow him the same rate of recovery.
