Heroic leap seems very buggy, but according to a couple of gms i've ticketed, its intended to be this way.
Can never seem to use it if my target is a single inch elevated, nor if there is a twig standing in the way. I guess i should be thankful it works when falling, although it really only helps me avoid fall damage, or ground pound in heroic ToT.
The idea is solid, although the execution seems a little silly. I can't trust heroic leap to save me, purely cause im scared it will bug out like 90% of the time and ill be left standing in the fire. Infact you can't use it at all in twins peaks for some reason.
Loved the idea of a leap ever since it was first introduced in the tbc/wotlk beta (Forget which one, either way it was dropped), but as it stands right now, i hate it.
What are you feelings on heroic leap ?
