Right so this is basically a macro where you could watch as far as you want with Far Sight.
1: Escape and make a macro
2. Make the macro like this : /cast !Far Sight
3: Click anywhere u want to watch
4: When u are seeing from that point of view, click the macro again and u can go further.
5: Have fun and watch the hordes while u are waiting at a battleground to start! You can also do other imba stuff ofc, an example is watch the bosses of high-end instances
Cheers
