Sometimes we houserule, that you can make ONE jump, so you can avoid only one intercept.
The skill is realy strong for Shadow Warriors with "See in the Dark".
Our group tends to use movementskills very often. (Climb, Sprint, leap).
A Vampire, Skaven, Elf or Possesed with sprint and leap has 15+W6" charge range. Even if it fails you cant be charged by most of your opponents.
Leap is difficult to rule, if the model is subject to frenzy. What is the distance, he has to charge?
