Fel Rush Cancel Macro (Demon Hunter) (Patreon)

This macro essentially just stops the movement effect of fel rush.  This is very useful for pve where the movement effect can send you into the fire easily, though it isn't without its uses in pvp also. 

The macro is

/cast fel rush

/run local t = time() + 1 while time() < t do end

It is essentially just the normal freeze macro set to a minimum time interval  preceded by fel rush. 

When I looked through the archives before posting this to make sure no one had published it previously I discovered there had been a third-party hack which did the same thing,  and caused some controversy in the community. 

Blizzard apparently consider this a "major" exploit. You may wish to avoid discussing this with other players for that reason.
