Flame Rush has issues with uneven terrain

Generally, you should include:
Flame Rush is a dependable skill for certain builds and should work as expected

What went wrong?
Flame Rush requires a pixel perfect sircumstances - terrain flatness and no nearby obstacles in order to work. It is not happening all the time but quite often when we have uneven terrain and even though player can walk from point A to point B in a straight line, thus it is expected that Flame Rush can be used to traverse the same distance. For some reason, that doesn’t happen often and it causes player to trigger Flame Rush in place.

I am providing an example video that such thing can happen in safe areas as well for no apparent reason.
I appologise for the bad audio quality.
