Hunter Eagle Eye Macro-View Almost Anywhere In Wow Quickly (Patreon)

A viewer of one of my youtube videos by the name of Scotty contributed an amazing little trick to do with hunter's eagle eye.  

He explained that you could chain-cast the hunter ability eagle eye. Normally what this ability does is allow the hunter to view an area as if they were standing at a targetted location, but you cannot normally repeatedly cast as you can with, say, shaman far sight, which can be torturously slow to execute. 

The macro is simply:  /cast !Eagle Eye  

(the ! is important, it is not a typo). 

Why is this so useful? Eagle eye is instant cast (unlike shaman far sight which has a cast time) and will allow the player to view areas far away very quickly. This is VERY advantageous in PVP where quickly responding to attacks on the other side of the map and assessing the enemy's location is everything. I would go so far as to say that in most RBG's where teams are evenly matched, this ability is decisive.

Eagle Eye will also go through walls and is currently to my knowledge by far the fastest way of viewing inaccessible areas for exploration purposes.

This workaround almost certainly has other applications with other spells/abilities/items.
